Va Va Voom! Selena Celebrates Mag Cover in Her Sauciest Look Ever

Justin Bieber, eat your heart out.

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."

Gomez has been a Disney darling and in the spotlight for years, but the actress/singer told us she is embracing the fun of growing up in front of the world.

"These shoots are fun. At the end of the day, I'm 21, so of course I'm very proud to be a woman and I'm proud of my body," she said with a smile. "It's just about doing it the right way."

Another thing Selena is proud of? Girl power. In the latest issue of Flaunt, Gomez addresses Lorde's recent criticism of her song "Come & Get It."

"That's not feminism," she told the magazine. "[Lorde is] not supporting other women. That's my honest opinion, that's what I would say to her if I saw her. I actually covered her song in all of my shows that I've done so far. I'm not sure if I'm going to continue that.”

Selena's remarks about feminism are similar to what Jennifer Lawrence said on Wednesday during her Tumblr Ask with Yahoo CEO Marissa Mayer, where she criticized certain parts of our culture for tearing women down.

"Of course [I agree with Jennifer]," Selena told us about Lawrence's remarks. "Honestly, that's all the questions that are being asked to girls nowadays. People are trying to find a way to get you to say something negative, and unfortunately that's just what — it isn't our fault!"

In the spirit of all things positive, Selena went on to give the Oscar-winning actress a thumbs up on her new 'do.

"She is rocking the hair! Rocking the hair, ah it's so good," Selena gushed about the "Catching Fire" star's pixie cut.

See? Girls in Hollywood can get along!
