From undercover to underwear: Sandra Bullock flashes built-in bra in sexy Beckham dress at London premiere of The Heat
She's a seasoned red carpet pro who isn't the usual type to flash her underwear.
However, Sandra Bullock went for a different look at the screening of her latest film as she opted for a dress with built-in bra that was actually meant to be on show.
The Oscar winner, 48, showed off her toned back in a black silk Victoria Beckham gown as she attended the gala screening of her new movie The Heat in London on Thursday.

Peekaboo: It appeared Sandra's decision to flash her bra was completely deliberate
The mother-of-one was clearly going for a more relaxed look in the silk dress, which she teamed with a wide belt and cage heels.
Arriving at the Curzon Mayfair, she left her brunette hair down in a tousled look, with minimal jewellery.
However, she was lacking her leading lady Melissa McCartney, who co-stars alongside Sandra in the crime caper.

The Heat, directed by Paul Feig, stars Sandra as FBI Special Agent Sarah Ashburn, who teams up with Melissa's Detective Shannon Mullins to hunt down a Russian mobster.
Director Paul was in high spirits as he arrived in a pinstripe suit and bowler hat.
He had some of the assembled crowd in giggles as he larked around with his cast Jessica Chaffin, Jamie Denbo and Katie Dippold.

Also in attendance was former Made In Chelsea star Kimberley Garner.
In contrast to 24 hours previously, when she flashed her legs, clevage and back in a daring ensemble, this time she was a lot more demure.
The swimwear designer wore her signature colour white with a pair of skinny jeans and lace blouse, which she teamed with a black blazer.
