Justin Bieber is working on his ''guns''.
The 18-year-old 'Boyfriend' singer - who is dating Disney star Selena Gomez - has started training every day in a bid to build up his biceps.
He said: ''I play basketball a lot, I train every morning with my trainer, we've been getting it in. We do a lot of body weight stuff, just trying to get some guns.''
And he believes a simple touch can make or break a man's muscle ego.
He told Access Hollywood: ''You can make someone either feel good about their arms or bad about their arms by the way you squeeze it.''
When it comes to his style, the 'Baby' hitmaker said he likes to mix things up and keep it exciting.
He said: ''I just want to be young and fun. I want to just be me and whatever that is, it is.''
Dressed in a yellow watch, shirt and trainers, he joked: ''I think that people should all wear yellow shoes!
''I have a bunch of kicks, I like shoes. I want to just be me and whatever that is, it is.''
