Mary-Kate Olsen: Not Dating Hunter Parrish!

Move over Hayden Panettiere and Milo Ventimiglia. You Heroes hotties aren't the only the only TV co-stars to blatantly lie and say you're not dating!

"It's not true," says Weeds star Hunter Parrish to Us Weekly regarding a Star Magazine report that he's dating new guest star, Mary-Kate Olsen.

Perhaps the Full House vet is just too frickin' weird talented.

"She's a very good actress," Hunter Parrish says. "And fun to work with... I'm sure we'll laugh about these rumors this week!"

Hunter Parrish and Mary-Kate Olsen: more than co-stars?

All we know is that Parrish is responsible for some great Weeds quotes, and that the show's star, Mary-Louise Parker, is one of our favorites. And that Mary-Kate really needs some sort of style consultant. Or a mirror to start!
