“90210″ fans will have something to sing about this spring! Mexican pop star Diego Boneta will be joining the cast, TV Guide reports.

Diego will play Javier, a young musician, in multiple episodes beginning in May. The buzz is that Javier has a fling with Adrianna (Jessica Lowndes), whose story line will “become increasingly music-centric when she joins an all-girl band.”

This is the first time the Mexican heartthrob will hit the small screen in America, but he is no newcomer to the music screen. Diego (who has also gone by the names Diego Indigo and Diego Gonzalez) has been nominated for Latin MTV Awards and Latin Grammys. He took to his Twitter this past weekend to break the news: “I’m going to be on several episodes of the American Hit TV series “90210″!!!! I’m playing “Javier” an international pop-star!”

What we find most interesting about the introduction of Javier into the cast is that a few months ago, word on the street was that Adrianna was going to be in a whole other kind of relationship — with a woman. We heard that she’d be exploring her options and making a real love connection with a gay West Beverly student, Gia (played by Rumer Willis). It will be interesting to see where her sexy new Latin man fits into the mix. All we can say is: ay papi!
