Piven Scores Clooney's Ex

Another one of our imaginary husbands celebrated a birthday this past weekend. George Clooney’s 45th birthday party was held at the Green Valley Ranch outside Las Vegas. Although his on again and off again gal pal Krista Allen was not invited to the soiree, she did head on to Sin City and struck a lucky star. Allen who has been linked to Clooney, David Spade and any other celebrity that would look at her was seen canoodling with “Entourage" hottie Jeremy Piven at the Fantasy Suite Block Party that Palms Casino owner George Maloof threw to mark the opening of his ultra-exclusive suites that feature bowling lanes, basketball courts and stripper poles.

In more Clooney news, our hubby was spotted sipping “Robber Baron” with filmmaker Steven Soderbergh at Campbell Apartment in Grand Central Terminal and possibly talking about "Ocean's 13," which will feature Al Pacino and Ellen Barkin.
