Sandra Bullock attended the red carpet premiere of her new film The Heat on Thursday in London and flaunted her figure in a sexy built in bra dress.

The 48-year-old appeared to be showing off peaks of her black bra in the Victoria Beckham dress, but the gown was intricately made with a built in bra.

The Oscar-winning actress looked stunning and paired the silk dress with a thick belt and strappy stilettos. She wore her hair in messy waves and posed   with her red nails on her hips.

Her new flick, The Heat, directed by Paul Feig, stars Bullock as FBI Special Agent Sarah Ashburn, who teams up with Melissa McCarthy's character, Detective Shannon Mullins to hunt down a Russian mobster.

In an interview with BANG Showbiz, she recently gave a shout out to McCarthy,

"I would never compare any of my perfectly hot co-stars, who are equally hot and amazing, to each other," she said. "Melissa McCarthy's the hottest co-star of all time! Melissa McCarthy is my hottest co-star."

She said that her and McCarthy bonded throughout the film.

"We had little time to enjoy [during filming], but the way we enjoy our life is exactly the same. I never thought I'd meet someone that was as... I don't want to use the word twisted [as me]; the word 'off' might be more appropriate," The Heat star said. "We both have the same life sensibilities, and the same things we love to do, so it was a kindred spirit. I was very lucky. You don't get that."

Bullock also noted that they shared alot in common,

"Having kids connected us on a deeper level," she said in Parade magazine.. "And the things we're obsessed with outside of being a mom are the same, too: construction and house renovation.... We're kindred spirits in that world. If we had a beer den, with Barcaloungers-but our version of that-it'd be great."
