Eva's Sober and Sushi-Free Sin City Weekend

The Desperate Housewives actress skips the raw stuff at a sushi hot spot and sticks to water all night...is she expecting?

Eva Longoria Parker certainly knows how to keep the gossips guessing.

On Friday, the actress hit Las Vegas clad in an Empire-waist babydoll dress. She snacked on edamame instead of sushi or anything else raw at the grand opening of Yellowtail Sushi Restaurant and drank only nonalcoholic bevvies.

Later that evening, at Pure nightclub, the Desperate Housewives star sipped Fiji water as Wilmer Valderrama and the Hilton sisters did shots of Patrón.

While she did recently cop to putting on pounds for her character's storyline, all these signs seem to indicate Eva might be expecting.

Her rep had no comment—so let the bumpwatch continue!
