Selena Gomez looks all grown up in a retro one-piece

Selena Gomez is sporting some seriously sexy ‘60s glam in the California desert on what’s reportedly the set of her latest music video.

Eat your heart out, Justin Bieber.

The 20-year-old strutted around the retro Palmdale set in a bold and cheeky one-piece with a matching pair of cat-eye sunglasses, bouffant ‘do and kitten heels, according to the Daily Mail. She later added a floral jumpsuit, criss-cross frock and pleated cobalt dress to the mix. See the other looks here.

Since ending her run on Disney Channel’s “Wizards of Waverly Place” in 2012, Gomez has been ratcheting up her adult self and trying to break with her squeaky-clean image. On March 22, she’ll be shocking audiences in “Spring Breakers,” Harmony Korine’s spring break thriller co-starring James Franco and Vanessa Hudgens.

“Disney was my life and that’s all, in a way, that’s all I knew,” Gomez told MTV in an interview about the film. “So once that ended I definitely think it was good for me to go to an extreme like this. That’s what was so liberating about it. I felt so safe.... I was really able to push myself to places I didn’t even know I could go.”

Last month, Gomez hit Vanity Fair’s Oscar party with her pal Hudgens, wearing a frothy Atelier Versace gown. Two years ago, she was famously photographed making her debut at the very same party with then-beau Bieber.
