Justin Bieber may be one of the biggest pop stars in the world, but he enjoys normal things just like the rest of us!

On Friday the Biebs went to Griffith Park in Los Angeles with a friend, and he flashed his lovely smile when X17 photographers caught up with the boys. Biebs wore ripped jeans and a Metallica tee, along with a beanie. Seeing as it was over 80 degrees, it seems like Biebs wanted to hide his overly peroxided locks from us...

Justin has been busy prepping for his upcoming Grammys performance, and at a rehearsal on Friday, Bow Wow, who is the the social media correspondent for the event, shared a snapshot of the boys knocking back shots. We're curious as to what the show will be like -- Biebs' performance is being billed as the biggest one, and he hasn't been hitting the stage much over the last few months.

Later on, Bieber Instagrammed a picture of his little brother Jaxon, who is apparently in town for a visit. All together now: Awwwww!

My Favorite little man came for a visit
