Selena Gomez is getting sexy and stripping down!
The pop star was in West Hollywood on Sunday night shooting a new music video, when an eyewitness tells ET the 23-year-old gave crew members a look at her bra!
"At one point, Selena had to fix her shirt and she unbuttoned it in front of everyone, showing off her black bra," the eyewitness said of the tightly secured music video shoot. "Selena seemed to be in good spirits, was laughing and chatting with crew – very friendly to everyone."
The eyewitness also revealed that Selena only filmed for about five minutes, noting that her stand-in worked the same scene, in which Selena is arrested by a police officer, for almost an hour.
It's a slightly more adult theme for the Revival singer, who opened up last week about all of the fuss over her former relationship with Justin Bieber.
"It's really hard because I'm a nice person. I'm just tired of talking about it," Selena told InStyle UK, adding that getting back into the dating game has been difficult now that she's looking for something more mature.
"I hate it. It's hard," she admitted. "I feel like I look 16 sometimes, which is a bummer, because I would love to date older guys."
