No shirt, no bra, big ad campaign! Gwyneth Paltrow was hard at work in L.A. on Tuesday, Oct. 1, filming a sexy new ad for Hugo Boss. The 41-year-old offered a considerable peek at her chest while styling a black suit with nothing underneath.

Paltrow went shirtless and braless under the formalwear while strutting across a downtown L.A. street and posing for the camera. The Thanks For Sharing actress accessorized the look with a diamond necklace, tall black heels and her long blonde hair swept to the side.

Of course, this isn't the first time Paltrow has made headlines for skipping essential undergarments. At the Iron Man 3 Hollywood premiere in April, Paltrow ditched underwear in order to wear a sheer dress. She later told Ellen DeGeneres that "everyone went scrambling for a razor" to get her red carpet ready because she works "a '70s vibe."

Five months later, Paltrow went back on The Ellen DeGeneres Show and admitted she shared too much personal information. "I knew [the comments] had permeated when my brother in-law said to me like, 'I hope you're not going to bring back big b---,'" Chris Martin's wife recalled.

"But let's know that you're not doing that," DeGeneres said.

"Let's not say I am and let's not say I'm not," Paltrow teased. "No, I'm not. No. Are we going to talk about my pubic hair every time I come on this show?"
