The "What Do You Mean" singer, who was dressed in his signature hoodie and jeans combo, with a hat covering his new platinum blonde hair, asked the crowd to sing along to the "oldie but a goodie" that catapulted the former YouTube sensation into superstardom in 2010, while Bryan played along on the guitar and sang back up.

The pop star was in town promoting his upcoming fourth album, which is set to drop in November and features his current number-one single “What Do You Mean,” while Bryan, who is 34 years his senior, is gearing up to deliver his thirteenth album, "Get Up", on October 16. The Universal Music label-mates have never worked together before, but based on their recent jam session, fans are sure to be clamoring for an Adams/Bieber collaboration.
