On Saturday night January Jones appeared on “Late Night With Jimmy Fallon”.

She challenged him to a second round of ‘Beer Pong’ after failing to beat Jimmy on her previous visit.

She wasn’t there just play Beer Pong, the Emmy-nominated actress was there to promote season 4 of the hit series ‘Man Men’.

The star looked radiant on the show wearing a Marchesa Resort 2011 dress.

Her geometric-print hand-embroidered cocktail dress with a fringed hem was the perfect choice for a Late night Saturday show.

The dress gets a 10, her hair gets a 4.

I wish she’s done something more interesting.

If you’re wondering what shoes she wore you can see in the video she wore black pumps.

Shocker.
