Daily Chisme: Eva Longoria and Mark Sanchez Split

Hola, chismosos! Ready for the daily dirt? Here's what's been happening in Hollywood:

- Eva Longoria and Mark Sanchez have called it quits, reports TMZ. "Eva's rep has confirmed the two have officially called it quits after several months of dating." So sad! Keep your head up, Eva!

- Speaking of Eva, the actress and Obama reelection co-chair has teamed up with a conservative Republican group after a recent anti-Mitt Romney tweet left them outraged, reports Fox News Latino. She had apologized, citing Twitter problems, but is now teaming up with the group, Cafe Con Leche, to work towards pushing for comprehensive immigration reform. 

- Are Rumer Willis and Wilmer Valderrama hooking up? It certainly seems that way! Radar Online got exclusive pictures of the two hanging out in Cancun at the Hard Rock Hotel. While Wilmer took shots straight from the bottle and Rumer paraded around in a sombrero, the two were also seen hugging during the event. What do you think? 

- Christina Aguilera's new album Lotus is hitting stores in just a matter of weeks, but the singer isn't putting down her old album, stating that Bionoic's lack of success was because it was "ahead of its time." That's one way to look at it, Xtina.
