Usher, Keri Hilson and Trey Song rocked the sold out Philips Arena on Saturday with their fiya remix to Trey’s “I Invented Sex.” Afterwards, the rumor mill cranked up with whispers that Trey and Keri were more than friends.

A source who was in the trio’s dressing room said Trey couldn’t keep his hands off Keri. “They were acting like school kids in the throes of puppy love,” said the source who asked to remain anonymous.
