Welcome to the onesie club, Selena Gomez!
Last night, the 19-year-old starlet flaunted a whole lot of sexy skin during a performance in Puerto Rico when she took the stage in a superskimpy outfit.
Justin Bieber's girlfriend wore a plunging blue gown that revealed plenty of cleavage, while her maxiskirt wrapped just around her backside, showing off her legs in a bedazzled bodysuit.
"Puerto Rico-- 4 hours til show time," Selena had gushed on Facebook beforehand, "so excited to be back such a fun place to kick off my South American Tour it's like my second home. Love you all."
But with a long skirt covering part of her assets and a fairly low-cut bodysuit, is Selena's sexy costume classier compared to Miley's? What do you think of the star's look? Weigh in below!
