Justin Timberlake celebrated his 30th birthday with a chilly dip in the Pacific Ocean on Monday, January 31.

No, JT’s shirtless dip wasn’t part of some bizarre birthday rite, he was simply braving the freezing waters while filming a scene for his new movie, Now. Justin looked pretty cold when he jumped into the waters but his hot body must have kept him warm after the initial temperature shock.
