Eva Longoria Parker's Sober Sin City Weekend

Eva Longoria Parker must be loving the attention she's getting from the pregancy rumors, because she doesn't seem to be doing anything to squash them. The increasingly voluptuous star was, uh, "partying" in Las Vegas this weekend, sporting her ever-present empire waist dresses and sipping on water and fruit juice.

On Friday, Eva attended the grand opening of the Yellowtail Sushi Restaurant, but skipped the raw fish in favor of edamame, and passed on sake and other cocktails as well, opting for non-alcoholic drinks.

After dinner, the actress hit up Pure nightclub with Wilmer Valderamma and Paris and Nicky Hilton (random!), but sipped on Fiji water instead of downing shots of Patrón with her friends.

At this point, we sincerely hope Eva is pregnant, because otherwise there's just no excuse for walking around in grandma dresses and drinking water at the club. She should just come clean already before people start assuming she really is morphing into a desperate housewife!
