The 'Call Me Maybe' star says Justin was "so sweet" to invite her to perform at the Capital FM event.

Carly Rae Jepsen says Justin Bieber was "so sweet" to let her appear during his set at the Capital FM Summertime Ball 2012 this weekend.

The Canadian singer-songwriter was introduced on stage at Wembley Stadium yesterday (9th June) as Justin's surprise mystery guest halfway through the 'Boyfriend' singer's performance set.

While talking to Capital FM after the event, the 'Call Me Maybe' singer says she had an "amazing" time and is grateful to Justin for letting her join him on stage.

"It was amazing. I had a great time," Carly told Capital FM yesterday after her performance of 'Call Me Maybe'. "Justin was so sweet to let me in on his set."

"I loved it when they sang along, the energy, you could feel it," she explained. "It was the best feeling in the world."

"[Justin has] been fantastic," the singer added, regarding her mentor Justin. "He hasn't really taken on the boss role, he's just been probably my greatest supporter so far. Yeah, a friend. A work colleague and a friend."

This year's Summertime Ball also saw show-stopping performances from artists like Usher, Katy Perry, Jessie J, The Wanted and Ed Sheeran.
