Careful, He Might Punch You Out

Justin Timberlake looks like he’s ready to deck the paparazzo snapping his pic as he leaves a London recording studio on Thursday.

The singer is working with Madonna on her new album and playing five sold-out nights at London’s O2 Arena.

And, word on the street is that JT is set to make a surprise appearance during Duran Duran‘s set at this weekend’s Live Earth concert.

Timberlake has been working with them on their new record as well.

He’s just so in demand!
