When Mary-Kate and Ashley Olsen launched their mens collection for Elizabeth and James, it was only a matter of time before Hollywood guys caught on.

Sure enough, Elizabeth and James for Men has been popping up all over Gossip Girl, including on Dan Humphrey in the now-infamous threesome scene.

Maybe it was the clothes that turned O and V on ...

Penn Badgley wore the Elizabeth and James Easy V Cashmere Sweater on the show, as you can see above, but it wasn't the first appearance for the line.

Dan wore two Elizabeth and James designs a week before the threesome, and last month Chuck Bass (Ed Westwick) sported an Elizabeth and James suit.

Looks like a brand Gossip Girl hunks can depend on!
