Justin Regifts His Junk

Justin Timberlake revived his hit video from SNL by hitting the stage in NYC ... with his d**k in a box!

The superstar singer had fans on their feet last night at Madison Square Garden when he surprised them by appearing in full costume (box included) and reenacting the "D**k in a Box" song with Andy Samberg.

That's one present Cameron is going to miss next Christmas.
