Selena Gomez and Justin Bieber kissed backstage at the 2013 Billboard Music Awards held at the MGM Grand Garden Arena on Sunday (May 19) in Las Vegas.

Earlier tonight, Justin and will.i.am performed That power on stage, and you can watch their performance here.

Meanwhile, Selena rocked the stage Bollywood style with her rendition of Come & Get It. The 20-year-old wore a sexy gold corset with a matching long slit skirt –very reminiscent of Princess Leia of Star Wars! I am sure Justin will be cashing in on the song’s lyrics and taking Selena up on her offer later on in the evening…

Watch Selena and Justin sneaking a kiss backstage in the video clip below, and then check out the amazingly funny gif of Taylor Swift making a disgusting face as she catches her bestie kissing JB:
