We all have to grow up some time and former Spy Kids star Alexa Vega has been doing a lot of growing up recently. She stars in Robert Rodriguez‘s Machete Kills as a femme fatale-like character named Killjoy – seems appropriate for this kind of movie. While she previously posted a picture of herself before shooting her scene, the photo below is the first official image of her on set.

Check it out the photo here below, and make sure your boss or significant other isn’t around (no, no there is no nudity).

Vega is now 24, and obviously she has really grown up to be a very sexy mature young woman. Hard to believe that she was that young child in those silly Spy Kid films. She revealed the new image of herself on her instagram account.
