DJ AM Pulls OT on Bday

DJ AM had to work a birthday party this weekend ... his!


AM took up his usual spot at PURE nightclub in Las Vegas on Saturday night, but this time he had pal Travis Barker by his side for an incredible birthday set. Neil Patrick Harris looked on as AM spun the tracks, while Barker rocked the drums live -- with a cigarette in his mouth! Now, that is rock 'n roll.

The Caesars Palace club, where AM spins every Friday, even gave him a cake shaped like a turntable -- which actually turned! You won't find that at Baskin-Robbins.
