AnnaLynne McCord attends Access Hollywood’s “Stuff You Must…” lounge (produced by On 3 Productions) celebrating the Golden Globes at Sofitel Hotel on Friday (January 15) in Los Angeles.

The 22-year-old 90210 starlet has finally jumped on the Twitter bandwagon with the handle @iamannalynnemcc. “I finally did it!” she said in her first tweet. “I actually AM AnnaLynne McCord to all you identity thieves!”

AnnaLynne used her first couple of tweets to bring attention to a few charities that are especially meaningful to her. She wrote, “Haiti needs our help, desperately! I was there 3 weeks ago volunteering with Artists for Peace and Justice! Please donate to them!”

She continued, “As you guys may know I work with St. Bernard Project building homes inn NOLA (New Orleans, Louisiana)! I will be in NOLA rebuilding houses in March! But in order to continue the work we need your votes… Facebook/Chase Bank is donating $1M to the organization with the most supporters! Please help me this would mean so much!”
