After two-and-a-half years together, Jessica Alba and Cash Warren have split. The 26-year-old actress broke up with Warren, a 28-year-old producer, last week over the phone, sources tell Usmagazine.com.

Sources tell Us that Alba, who was abroad over the weekend promoting Fantastic Four: Rise of the Silver Surfer, called Warren on July 22 and told him, "I'm not in love with you anymore." Within hours, Alba had dispatched an assistant to the L.A. home they shared to pack up Warren's belongings and move him out.

Warren and Alba met on the set of Fantastic Four in 2005, when Warren was the assistant to the film's director, Tim Story.

Despite the gap between them on the film industry food chain, the couple were often seen partying at Hollywood events and enjoying romantic vacations from Mexico to Miami.

In 2005, months into her relationship with Warren, Alba told Us, "being in love has made it a hot year."

Just a month ago, Spike TV named Warren the "Luckiest *******" of 2007 at their first annual Guy's Choice Awards, due to his relationship with Alba.

But now, a source tells Us that Warren isn't feeling lucky at all and is, understandably, very upset.

The breakup "happened...almost out of nowhere," the source says. "[Cash] thinks its for another guy but doesn't know....he's totally devastated. But it was all her."

Alba's rep declined to comment.
