Andy Cohen reveals the 'N Sync member's prom photo on Watch What Happens Live.

on Oct 7, 2013 - The Dish

No celebrity's secrets are safe when they hit the Bravo Clubhouse and Andy Cohen decides to "Open the Vault," and on last night's Watch What Happens Live former 'N Sync member (and current satellite radio host) Lance Bass got the chance to explain who he took to prom: Boy Meets World star Danielle Fishel. Yes, Topanga!

The classic prom photo features Bass with spikey, bleached-blonde hair and a black tux awkwardly wrapping his hands around Fishel, who's decked out in a white dress with cutaways and a wrist corsage.

"I get so much crap for that," the openly gay (and engaged!) Bass admits, referring to the way his hand is positioned on Fishel's hip in the photo. "It was just a shot of my hand about to grab her. It looks like, 'I don't want to touch her!'"

Watch Andy reveal that Lance Bass went to prom with Boy Meets World star Danielle Fishel and tell us in the comments: are you surprised Bass used to hang with Topanga?
