On this week’s new episode of 90210, the first in months, viewers saw two girls kissing.

On Tuesday’s installment, we’ll be treated to the opposite end of the sexy spectrum: two girls fighting!

Aptly titled “Girl Fight,” the hour focuses on the growing feud between Naomi and Ivy, as the former realizes the latter still has feelings for Liam. How does this rivlary culminate? Watch the clip below here.

Also on tape Tuesday night:

* Jasper shows Annie photographic evidence of her hit-and-run.
* Adrianna and Gia throw themselves a pity party.
* Silver and Teddy consider a relationship.
* Kelly Lynch guest stars as a new love interest for Ryan.

As always, we’ll recap, review and run down the latest 90210 music after this episode airs. In the meantime, check out a few photos from it:

Adrianna kissed a girl, and she liked it.

At least, she thinks she might have liked it.

“That’s the twist!” said Canadian Jessica Lowndes, who plays Adrianna Tate-Duncan in 90210. The series returns this week, Tuesday on CW and Thursday on Global.

In a new episode titled Rats and Heroes, Adrianna and Gia — played by Rumer Willis, daughter of Bruce Willis and Demi Moore — lock lips after attending an Alcoholics Anonymous meeting.

“Adrianna has a very addictive personality, addicted to the highs and the lows,” said Lowndes, 21. “In the episode just before the break, she made a commitment to quit drugs and try to stay on the straight and narrow.

“She still has feelings for Navid (played by Michael Steger) and she’s doing everything possible to prove her love for him. So she goes to AA and meets this girl named Gia, played by Rumer Willis.

“Through different compromising situations that Adrianna finds herself in, Gia is really there for her and they share a special bond. Adrianna starts truly questioning her sexuality. So that’s definitely going to be something.”

But that’s not the only influence Gia has on Adrianna.

“Gia encourages Adrianna to take her sadness over Navid and put it into music, which has been amazing for me,” said Lowndes, who is embarking upon a music career herself. “I’ve been able to incorporate a lot of music into the show.”

In fact, Lowndes — who hopes to have a full album out by the end of the year — gets to sing in virtually every remaining episode of 90210 this season.

“It’s so exciting, and all different musical styles, as well,” Lowndes said. “It’s awesome that we got a third-season pickup and there’s going to be a lot more music in the third season as well.

“That’s what I’m doing when I’m not working on 90210, I’m working on my album. So I love it, it’s a dream come true.”

Despite being part of the quintessential California lifestyle in 90210, Lowndes said Vancouver always will be home. She did make it back to Vancouver for the tail end of the Olympics.

“I went to the closing ceremonies and different medal ceremonies and hung out with my family, it was amazing,” Lowndes said. “Just taking in that Olympic spirit, I’ve never seen the streets of Vancouver like that.”

Lowndes did find herself in some traffic chaos, however.

“I made the mistake of driving downtown on the final Sunday,” she said. “(Public transit) was chaotic as well, so I was like, ‘Hey, let’s just drive, it’ll be fine.’

“Literally, there were people with Canadian flags, dressed all in red and white, just running in front of the car. It was pretty terrifying.

“But it was kind of great, because random strangers were coming up and high-fiving us. They were just so high on life. After we — and I can say we because you’re a Canadian — after we scored that goal to win the hockey game, horns still were honking six hours afterward. It was awesome.”

So let’s add this up:

Jessica Lowndes plays a character on 90210 who has addictions left, right and centre, so Lowndes gets to flex her acting muscles; the character now is getting to sing more and more on the show, which is Lowndes’ other passion; and oh yeah, Canada won hockey gold in her home town.

We’d say things are going pretty well for Jessica Lowndes. And that’s not even counting the kiss with Rumer Willis!

Catch Tristan Wilds on The Wendy Williams show tomorrow at 10A.M. eastern time on Fox! Reruns come on for the Wendy Williams show at 10PM eastern time on MyNetworkTV and 12A.M. eastern time on BET for those who can’t watch the first showing!

“90210″ will return to our TV screens this coming Tuesday (March 9) and we’ll have a lot of catching up to do with the boys and girls of West Bev.

But, heads up, a little birdie just gave Korbi TV some advanced info on Navid’s (Michael Steger) love life.

Seems the head of The Blaze is just beginning to get over Adrianna (Jessica Lowndes) — who definitely seems to be moving on too — and he will start dating one of his staffers later this month.

Navid’s new lady is that chick Lila — she’s played by actress Amber Wallace — and she looks a bit different than the other girls we’ve gotten to know on the show.

But she’s still beautiful.

See for yourself…

Diana in Memphis, Tenn.: I’m so ready for 90210 goodness. What’s coming up the next couple of months?
For AnnaLynne McCord, it’s going to be a lot of 90210 badness! We chatted the actress up at the Ecco Domani Fashion Foundation event and she told us, “The finale is always brutal for Naomi. It’s always the worst thing in the world. She has it horrible! The last thing of the finale is Naomi’s face, and it’s really bad. What happens to her is awful. So I kinda feel like there will be some downward spiral in a way for Naomi’s character, but she’s good at covering, so she’ll still have that façade. But you’re really gonna feel bad for her at the end of this episode.”

Perry in Milwaukee, Wis.: Naomi and Liam are my favorite 90210 couple. Any scoop on them together?
Yes! AnnaLynne told us there’s a lot of Naomi-Liam goodness to come on 90210. She said, “Matt Lanter and I have so much fun together. We love working together. There are some hysterical moments that I don’t recommend 16-year-olds doing at home, one of which where Naomi shows up with a trench coat and, well, nothing else…’cause that’s smart.” Does that work out for her? “It works out! Oh, it works out quite well.”

Pam in Kentwood, La.: I can’t wait for 90210 to finally return, and I’m really interested in the Rumer Willis-Jessica Lowndes storyline. What can we expect?
When it comes to the budding Gia-Adrianna romance, you can expect tons of good things. Rumer and Jessica actually have loads of chemistry, and while their attraction to each other seems to develop a little quickly, this is one 90210 storyline we’re fully onboard with. Adrianna and Gia bond over mutual sobriety, then music and movies and ice cream, and pretty soon, they’re in young love. Before the two move ahead, Ade will question her sexuality and turn to her besties for help. The consensus? She’s not gay, just has a connection with Gia.

AnnaLynne McCord recently revealed some major 90210 spoilers.

She said that when the show returns, things will get even tougher for her character, Naomi. She said that the finale will particularly be tough.

“”The finale is always brutal for Naomi. It’s always the worst thing in the world. She has it horrible! The last thing of the finale is Naomi’s face, and it’s really bad. What happens to her is awful. So I kinda feel like there will be some downward spiral in a way for Naomi’s character, but she’s good at covering, so she’ll still have that façade. But you’re really gonna feel bad for her at the end of this episode.”

I need to know more about Delko’s undercover investigation of the lab on CSI: Miami. What’s he going to find? — Marshall
ADAM: “That investigation will reveal the most dramatic betrayal in Horatio Caine’s career,” co-executive producer Barry O’Brien tells us. “It puts Horatio in a light we’ve never seen him in before, questioning the loyalties of his team. … It will rock the fabric of the team and threaten at least one — if not more — CSI’s future.” Hmm, maybe that’s the reason Delko will be back full-time next season.

Will Dixon and Silver ever get back together on 90210? — Dana
MICKEY: For now, Dixon and Silver are dunzo, if only because Dixon will be busy (mentally, anyway) when his birth mother shows up in Beverly Hills, and Silver will be preoccupied with whether new beau Teddy is as much of a player as he seems. (Answer: Duh, yes.) Plus: Ivy will help Naomi with an unexpected project, Navid will get into some unexpected trouble, and Ade will be tempted by wine, women and song.

Congratulations are in order for Gillian Zinser. The actress has been promoted to series regular on 90210.

Zinser debuted on the show toward the end of 2009. We thought her character’s introduction and subsequent love/hate relationship with Liam felt forced, but Ivy eventually settled into her role on the series.

She now makes for the ideal foil for Naomi, as a promo for the second half of the season makes it look like as though these two aren’t done fighting over Liam. Not one bit.

Are you happy Zinser is now a regular part of the 90210 cast? Do you wanna see Ivy or Naomi end up with Liam? Sound off now!
