*NSYNC played a game of Never Have I Ever on "Ellen" yesterday, and Ellen asked the guys if they'd ever hooked up with a SPICE GIRL.
Four of the guys immediately said no, but JUSTIN TIMBERLAKE did enough hemming and hawing to make it obvious that he HAD. He wasn't asked to elaborate, and he didn't offer any details on his own.
But in a 2004 interview on British TV, EMMA BUNTON pretty much admitted it was her. In other words, Justin delivered the goods to BABY SPICE! (Here's that interview. Skip ahead to 7:22.)
