Listen to Selena Gomez on iHeartRadio

(Yahoo!) - Selena Gomez stepped out to celebrate her Flaunt magazine cover on Thursday night at Hakkasan in Beverly Hills looking absolutely gorgeous in a cut out, black Cushnie Et Ochs dress, a sauced-up sexy look similar to the photo spread in the magazine where the "Slow Down" singer, 21, poses in a bob wig, lingerie, and some fabulous couture.

"Well, I actually really was tempted to wear the bob!" Selena told omg! about her ensemble for the evening. "I loved it, it was so much fun, so I wanted to do something darker and simple [tonight]. I've been running around, so something simple was key."

In the latest issue of the magazine, Selena looks more grown up than ever, in a shoot that British photographer — and host of "The Conversation" — Amanda de Cadenet told omg! was purposefully "sensual, not sexual."

"Whenever there's an opportunity to photograph a role model in a way that isn't sexualized — at this time in her life, I think it was a really important shoot for her to do that kind of shows how she is," Amanda told omg!. "She has a lot of integrity."

So did Selena ever have reservations about it?

"[Amanda] and I actually have very freaky stories," she told us. "We have similar kind of backgrounds with her daughter who is 21. She had her daughter when she was 16 and my mom had me when I was 16, so there was a level of sophistication that she knew I was trying to come across, because her own daughter in her life is doing that, so it helped."
