Ivanka and Lance Armstrong?

Ivanka Trump is gorgeous, successful, and . . . dating Lance Armstrong? Though hard to believe, that's the rumor on the West Coast. And Trump, who will be the new spokeswoman for Tiffany as well as working at her father The Donald's firm, has been spending a lot of time in L.A. recently shooting "The Apprentice." Armstrong is also known for having an eye for hot women and was most recently linked with Paris Hilton. A rep for Trump didn't return calls.
