Rosario Dawson and Jason Lewis?

I didn't even know they were together, but I guess they aren't any more. US Magazine is reporting that Rosario Dawson and Jason Lewis have called it quits! The couple began dating in 2004 and had been living together in Hollywood since November 2005.

"[Rosario] was telling people a few weeks ago that they're over. She's really upset," a source tells Us Weekly. As recently as October 23, the couple were videotaped by TMZ enjoying an extended hug outside an L.A. restaurant. The Web site called it “one of the longest celebrity hugs ever caught by a paparazzo's lens.” The site added, “It's nice to see young actors so clearly nuts about each other.”

No word yet on why the couple called their relationship off. However, in March 2006, Dawson confided to Britain’s Culture magazine that the attention her boyfriend gets from other women can be difficult to handle. "Every time we go to a party, Jason is soon surrounded by a group of women of all ages,” she said. "They openly put their hands all over him - even between his legs - and ask him out. I am sitting there alongside him, watching all this." She added: "Even I have been surprised by their behavior. Yet I always think it is impossible to shock me."
