Celebrity Justin Bieber and Selena Gomez Kiss on Live TV What happens in Vegas is that the two smooched at the Billboard Music Awards By People Staff Published on May 23, 2011 11:50AM EDT So much for the slogan “What happens in Vegas stays in Vegas.” Unless it’s amended to include, “Just don’t do it on national television” – which was the case Sunday night, when Justin Bieber delivered a hug and a kiss to Selena Gomez upon his being named Top New Artist at the 2011 Billboard Music Awards. While both parties have long played it coy whenever confronted about their relationship (even by so formidable an inquisitor as Ellen DeGeneres), there was no mistaking their being together Sunday with his mother, Patricia Mallette, sitting next to them in the audience of the MGM Grand, chaperoning. And while Bieber thanked his mom and several others when he got his award, Selena’s name did not happen to cross his lips, even though she had just planted a big one on them a few seconds before.
