Hailey Bieber's Wild Birthday Antics at Kylie Jenner's Party Spark Reactions

Hailey Bieber let loose at Kylie Jenner’s 29th birthday party.

The Rhode founder attended her close friend’s birthday bash Friday, and reposted a wild shot of herself licking a female friend’s backside on her Instagram Stories.

The original shot was posted by influencer Devon Lee Carlson, and shows Bieber bent down and licking her friend’s left side while wearing a tiara, as the friend — whose face isn’t shown — is bent over a marble counter and holds a drink.
