Justin Bieber in 'training'
JUSTIN Bieber is in "training".
The 'All Around The World' hitmaker, 20, is reportedly building up his "stamina" for the new year.
A source said: "Justin's real main thing right now is getting in shape and training. He told us he's got big things happening in the new year and will need all the stamina possible.
"He said he's going to be in the studio around the clock and will be working on some tight sounds."
Meanwhile, another insider recently revealed that Justin is confident he will win back his ex-girlfriend, Selena Gomez.
The source told HollywoodLife.com: "Justin bragged that he's got so many girls, and could get any girl he wanted, including Selena."
The 22-year-old singer - who is rumoured to have given her former boyfriend until New Year's Eve to win her back - tried to "impress" the 'Come And Get It' hitmaker by posting pictures online from a "spontaneous" photo shoot on Twitter.
The insider revealed: "Justin's photo shoot was pretty much spontaneous.
"Justin hopes Selena saw the photos. He wants her to see how good he looks. How healthy he is and that's he's changing for the better. He hopes the pictures impress her."
