Odd Couple Alert: Ivanka Trump and That '70s Show's, Topher Grace

FORGET the Lance Armstrong rumors - Ivanka Trump spent Saturday night with her new man, "That '70s Show" star Topher Grace.

The well-upholstered heiress celebrated her 25th birthday in Las Vegas, where spies say Grace was Trump's date. They canoodled on the balcony during dinner at Social House with a group including Grace's former co-star Wilmer Valderrama.

Then, at nightclub Pure, they closed the curtains around their private table for a half-hour. The couple "never left each other's sides," said our source.

Odd match. But there's just something about Topher's scrawny that's always turned me on a lil bit too. Should I be seeking professional help?
