If at first you don’t succeed, try, try again. As Page Six reported last month, Bruce Willis was very eager to get tsunami model Petra Nemcova’s number - finally scoring it after he donated a large amount to her charity. Since then, the two have kept in touch. Nemcova has told pals: “He’s been really sweet to me, but I wouldn’t call it dating,” while Willis has told pals the two are dating. A rep for Nemcova declined to comment. We’ll see if she shows up to the premiere of “16 Blocks” tonight.
