(Cover) - EN Showbiz - Justin Bieber cant wait to see what Willow Smith brings to their tour, as he thinks shes adorable.

The Canadian star kicks off the European leg of his world tour on March 4, and has invited ten-year-old Willow to be his support act. He is looking forward to watching her perform as he knows shes going to pull something special out of the bag.

I'm excited to see what [Willow Smith] brings to the table," he said. "We start on March 4, so she's really excited, and she told me that she can't wait - and she's adorable - so I can't wait.

Before he embarks on the series of shows, Justin will celebrate turning 17 on March 1. Hes looking forward to his birthday, although he doesnt have much planned. The young star wont have a big blow out as he wants to make sure hes on top form when he hits the road.

I only have, like, four days, so I'm just going to relax, because I start my tour so [Im] just going to mentally prepare and just relax," he told Entertainment Tonight when asked about his plans. "No birthday bash... Hopefully my grandparents will be out here and I'll be able to spend time, a little bit, with them. My grandma makes the best cheesecake - cherry cheesecake. She made that for my 13th birthday."

Justin debuted a new haircut earlier this week, opting to get rid of the famous floppy fringe which has made him a hit with teen girls worldwide. Much has been made of the decision as his tresses were such a key part of his overall look, and Justin finds the interest strange.

He insists he didnt spend long debating whether to go for the chop, revealing it was more of a spur-of-the-moment thing.

I just wanted to [cut my hair], that's all. Not really a big reason; I just woke up and said, 'I don't want this anymore,' so I just cut it," he explained. "It's not really about that. You know, the fans really liked it, but they'll like me no matter what, because I think it's about the music. I'm really excited to see what the fans overseas think and take it day by day.
