Justin Bieber hat tank top

After hanging out with his family and ladylove Selena Gomez over the last few days, Justin Bieber is back in the studio and back to preparing for his highly-anticipated Believe tour. The concerts kick off late next month in Arizona, and the 18-year-old pop sensation will be making stops in 86 cities (51 dates in North America, 35 in Europe).

Biebs tweeted yesterday, "and yes we are in rehearsal again getting real sexy for the tour. real sexy...i mean real sexy. so sexy right now. #BELIEVEtour."

We'll take his word for it!
