Justin Timberlake kicked off the season 8 premiere of Ellen's show today, busting out a couple of signature moves at the top of the show.

Timberlake, who has taken a break from singing (and dancing!) to concentrate on his acting career, also brought a little surprise for the audience -- a clip from his new film The Social Network where he's shirtless!

"It feels a little gratuitous now," a shy Justin said after hearing deafening screams from the audience.

Gratuitous or not, we cannot wait to see it on a 30 foot screen!
