In a post on her Twitter.com page she writes, "Got news that my big bro Justin Bieber invited me on his European Tour in March. So exciting! Maybe I'll let (brother) Jaden come. LOL (laugh out loud)."
Justin Bieber confirmed the news by re-Tweeting Willow's message and teasing fans that he has some extra surprises in store for his My World Tour, writing, "Willow get ready... I got more surprises coming."
Justin Bieber also teamed up with Willow's older brother Jaden earlier this year (10) - they collaborated on a song for his Karate Kid movie.
