Justin Bieber may have entertained thousands of screaming fans last night during his first UK show of the MyWorld tour, but today the Biebs wasn't having it as he snuck out of the back of his hotel to avoid the waiting throngs in front.

Justin seemed pumped for his first night back on the tour, tweeting "glad to be back on tour. missed all of my beautiful fans," before he took the stage.

But Bieber wasn't the only one pumped to be onstage, Willow Smith, who joined the UK tour as Justin's opening act, tweeted "the show went GREAT!!! Thank you, Birmingham!"

Justin and Willow are taking on a second night in the UK city as we speak.
