Johnny Manziel isn't hiding before training camp. He's hanging out with pop star Justin Bieber.

The Browns' rookie quarterback promised last week he wouldn't change his ways despite Hall of Famers Emmett Smith and Joe Montana urging him to tone down his lifestyle.

That didn't stop him from posting photos on Twitter of him with Bieber and champion boxer Floyd Mayweather. Manziel says he's tired of all the talk about how he spends his free time and doesn't think he's hurting his career.

He insists he's "not going to change who I am for anybody. ... I'm very committed to football."

After attending the NFL's rookie symposium last week, Manziel visited the Pro Football Hall of Fame on Saturday and spent Sunday in Cleveland filming a TV commercial.
