Alexa Vega is determined to show she's not a kid anymore. Starring in the 2001 movie Spy Kids alongside Hollywood heavyweights Antonio Banderas, Teri Hatcher and Alan Cummings, Vega is now 24 years old and ready to flaunt her sexuality on the big screen.

Following in the footsteps of Rihanna and Kim Kardashian, Vega has been posting a slew of sexy shots of herself on Twitter but it was the one of her in nothing but a bra and black leather chaps that caught the media's attention. The scantily-clad ensemble is for her new movie Machete Kills.

"The first time I walked out in my outfit on set, everyone was like, 'Wow, you're not allowed to wear that,'" the former child star told The Hollywood Reporter. "This was all about owning my sexuality. I worked really hard for it in a way that I never had to work hard for something else before,"

Machete Kills also stars sexy starlets Sofia Vergara, Lady Gaga and Amber Heard, and isn't set to hit theaters until April 11, 2013. The sequel to director Robert Rodriguez's Machete follows the U.S. government as they recruit Machete Cortez (Danny Trejo) to battle his way through Mexico in order to take down an arms dealer who looks to launch a weapon into space.
