Selena Gomez performs at Z100's Jingle Ball at Madison Square Garden on December 10th, 2010.

As Jessie J continues her ascent to full-fledged stateside pop stardom, Selena Gomez gives the U.K. singer a leg up, performing her hit "Price Tag" at a gig Sunday (Mar. 6) in Houston.

Gomez put her own sweet spin on the feel-good, "more money, more problems"-preaching hit, which features rapper B.o.B. As Jessie J says, "money can't buy you happiness," but hey, maybe Justin Bieber can. Just ask Selena, who's looking pretty happy in the clip.
