Girls gone wild? Make that underage girls gone wild!

Rather than partying it up on the beach in California, Kendall Jenner, Kylie Jenner, Gigi Hadid, Bella Hadid and Hailey Baldwin let loose in Monaco, which it is totally legal for them to hit the clubs and party on yachts.

All of the ladies also attended the Grand Prix race on Sunday to support Lewis Hamilton, who Gigi is reportedly romancing following her split from Cody Simpson. Hailey posted the above snap of Gigi and an unidentified female pretending to lick and grope Kendall's boobs and wrote, "Everyone's always grabbin on Kenny," while Bella put all the ladies' bikini shots to shame with a selfie of her cheeks.

Justin Bieber wishes he was here! And interestingly enough, Hailey tagged him in one of the pics, which was of Kendall's foot. Such an odd relationship!

we're not ok 🙏🏼 @bellahadid
