Justin Bieber celebrated birthday in ice cave

Pop star Justin Bieber celebrated his 22nd birthday in an ice cave with a few friends.

The "Love Yourself" singer enjoyed acting like "a little kid" while on a snowy break with friends to a mystery location, which he flew out to via private jet, reported Female First.

The musician took to Instagram to post a video of him tobogganing down a snowy slope, which he titled, "This is a little kid smile."

The "Sorry" hitmaker posted numerous other uncaptioned pictures of his birthday outing on the social media site - which received over one million likes - including one showing his five friends sipping beers at the frozen grotto.
