Justin Bieber broke a million Biebettes' hearts when he packed on the PDA with GF Selena Gomez at the Billboard Music Awards, Sunday night in Las Vegas.

Bieber, who won six awards last night, went in for a kiss after his first win, but missed and got his lady's neck instead. After his second win "The Biebes" made sure he didn't miss, kissing Gomez smack on the lips for the world to see. Awww!

Hollywood's youngest power couple didn't walk the red carpet together, (she in a sexy black Dolce & Gabbana gown, he in a solid gold tux) but sharing a big public smooch during the event showed the Baby singer's fans he's definitely taken!
