Justin Bieber, who?
The brunette beauty surrounded herself with some seriously gorgeous guys while she sang her huge hit, and we have to say the 23-year-old has really grown into a killer live performer!
The former Disney darling rocked the show as she descended a dramatic staircase, and even threw in a dance break! This girl's got some serious moves!
We're a little bummed that ABC didn't cut to JB at all during the performance, because we'd LOVE to see the former flame's reaction to his ex getting all handsy with her HOT backup dancers!
Ch-ch-check out Selena SLAY (above)!
