Justin Bieber Heads Out on a Pre-Birthday Hike!

Justin Bieber is getting in some pre-birthday exercise!

The 22-year-old entertainer was joined by a male friend as he stepped out out for a hike on Tuesday (February 28) in Studio City, Calif.

Justin is just a day away from celebrating his 23rd birthday and we’re sure he has some big plans!

Perhaps Justin will be hanging with his rumored flame, model Ashley Moore, who he was spotted out on a hike with earlier in the week.

Justin has known Ashley for quite a few years and spent a lot of time with her in 2013, when they were spotted at parties, getting lunch and attending basketball games.
