Justin Bieber Adds Willow Smith To European Tour Lineup

'Whip My Hair' starlet tweets the news about My World Tour dates kicking off in March.

Beliebers, get ready to whip your hair. Willow Smith announced on Wednesday (November 8) that she'll be joining Justin Bieber on the European leg of his My World Tour, which begins in March.

The 10-year-old Roc Nation star took to Twitter to dish about hitting the road with the teen sensation: "Got news that my big bro @justinbieber invited me on his European Tour in March.so exciting! Maybe I'll let Jaden come..LOL #NEVERSAYNEVER."

But the addition of Willow to the European trek lineup may not be the only surprise Bieber has up his sleeve. Shortly after Smith's tweet, Bieber re-tweeted her message and replied, "@OfficialWillow get ready...i got more surprises coming. #MYWORLDTOUR."

But before Smith teams up with the Canadian pop star, the 10-year-old will celebrate the end of her roller-coaster year with an appearance on "Dick Clark's New Year's Rockin' Eve With Ryan Seacrest 2011."

Earlier this year, Bieber collaborated with Willow's older brother Jaden on a song for the soundtrack to Jaden's "The Karate Kid" remake. The video for Bieber's "Never Say Never" showed the duo recording the track in a studio.
