Star Tracker: Christina Aguilera, Christina Milian, Michael Trevino and more...

- Things got a little out of hand when Christina arrived in Brazil this weekend. Hundreds of fans waited for her at the airport and lined the streets just to see her arrive. The pop star tried plowing through the crowd but was mobbed in the process! Scary stuff!

-We know the Biebz is everywhere these days but we didn’t expect to see him in the middle of The-Dream and Christina Milian’s divorce settlement. Apparently The-Dream agreed to pay Milian 10% of his publishing interest in Bieber’s hit single, Baby (a song he co-wrote), but Milian is trying to renegotiate the settlement by demanding a higher cut.

-Are Glee star Jenna Ushkowitz and Vampire Diaries cutie Michael Trevino dating? The pair was seen attending the 2011 Screen Actors Guild Awards and a few of the SAG after-parties together. Michael was also spotted with his arms wrapped around Jenna at Naya’s 24th birthday party.

-It’s not everyday you find a cabbie who can pull off such a killer Michael Jackson impression! That’s why we couldn’t stop the LOL’s when we saw this great video of a Brazilian cabdriver beat-boxing and singing like Michael to the delight (we think) of his customer. This guy is def a future star!
