Beyoncé -- Boobin' Out After Super Bowl

Call her Bouncé ... because Queen B advertised more breast last night than Popeyes.

Beyoncé was showing off the girls at Hennessy's Super Bowl afterparty in NYC, wearing a v-neck t-shirt that was so deep it was poetic. She and the twins got their groove on while Nas and Kelly Rowland performed on stage.

Proud husband Jay Z was there too ... but we all know what the real attraction was.
