Cody Simpson won a slew of hearts at his March 8 performance at the O2 Arena in London opening for Justin Bieber.

Even though almost everyone in the arena knew who he was, Simpson, whether humbly or not, took the opportunity to let the crowd get to know him.

"I want to thank my mate Justin Bieber for having me. And you, the fans!" he said. "I'm from Australia. I'd like to introduce myself. My name is Cody Simpson," he said, stating facts like an icebreaker on the first day of school. "I'm 16 years old. I was born and raised Down Under in Australia. I have two questions for you tonight, London. The first one, do you mind if I get a little uncomfortable up here?" Simpson then stripped off one of his shirts to shrieks that could shatter glass.

The second question? Simpson strapped on a guitar and asked, "Who would like to be my angel tonight?" Then, appropriately enough, the adorbs Aussie launched into an acoustic rendition of 'Angel.'

Simpson followed with 'All Day,' rocking a denim jacket and doing a choreographed chair dance, and closed with -- surprise! -- 'Wish You Were Here.' But it wasn't the end! He returned later to duet with Carly Rae Jepsen on 'Good Time,' which you can watch here.
