Tom Cruise and Katie Holmes really know how to throw a housewarming party! The couple invited 250 A-list celebrity pals - including Jennifer Lopez, Victoria Beckham, Oprah Winfrey and Tobey Maguire - to their just-renovated $35 million mansion in Beverly Hills for a no-expense-spared bash on May 31. Guests feasted on a lavish spread created by celebrity chef Wolfgang Puck, washed down with Dom Pérignon. "There was even a caviar section," says an insider. The couple, clad in white, greeted every guest personally. "Katie was very pleasant. She and Tom made sure everyone was having fun." And they made sure to invite their new neighbors, "Tom sent beautiful flower arrangements to each neighbor with the party invites put inside," says one. "They were amazing arrangements that must have cost hundreds of dollars."
