Justin looks pretty suave chatting up the singer — should Selena be nervous?

Justin Bieber is a taken man, but that didn’t stop him from chatting up some sexy superstars at the Feb. 20 NBA All-Star Game!

Rihanna, 23, looked positively smitten while talking with the 16-year-old superstar, and why wouldn’t she be? The duo were the prince and princess of NBA All-Star Weekend, with Justin taking home the MVP award at Feb. 18’s Celebrity Game and Rihanna performing a rousing halftime show during the Feb. 20 All-Star event.

Selena Gomez better grab her man if she doesn’t want him swept away by another known cougar!
