The former Disney star has a split personality in her latest gig!

Selena Gomez is coming up in the world! After several years toiling on Disney’s “Wizards of Waverly” series, the 19-year-old has a headline-making romance with teen idol Justin Bieber and the honor of hosting the 2011 MTV European Music Awards. Serena took on dual personas for the show’s promo video, appearing both as her pop star self in a sexy little outfit and as a gangsta rapper with some killer cleavage popping out of her pushup bra! We don’t know how well Selena will do as a host, but she’s looking hotter all the time!
