Trey Songz kicked off his first headlining tour “Passion, Pain, Pleasure” in Atlanta this past weekend. The 25-year-old singer pulled his special guest, R&B starlet Ciara on stage for a sexy on-stage encounter. “Don’t be scared,” he told her while massaging her back and kissing her on the neck. A giggly Ciara looked stunned, but seem to enjoy the impromptu scene.
