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!"

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!
