Sandra Bullock Flashes Bra at The Heat Premiere—See the Pic!

Actress was at the London premiere of her new flick costarring Melissa McCarthy

Business in the front and a party in the back!

Sandra Bullock flashed some major skin (and her bra) while strutting her stuff on the red carpet premiere of The Heat in London.

Bullock stunned in a black Victoria Beckham gown that showed off a built-in bra in the back. The gown appeared tame in the front, with a belt and high neck-line, but the actress showed off a whole lotta skin when she turned around.

The Oscar winner's latest flick costars Melissa McCarthy, whom she's become incredibly close with since filming.

"Having kids connected us on a deeper level," Bullock told Parade magazine.

So close in fact, that she revealed the two ladies have held playdates for their children over the past few months.

What's Bullock's latest next career move?

E! News has confirmed that she is in talks to join Jaime Foxx and Quvenzhané Wallis in Sony's remake of the musical Annie, which is being produced by Jay-Z and Will Smith.
