Let the games begin. Justin Bieber is out with his nerf guns and is ready for a little friendly fire with this pals Kendall Jenner and Hailey Baldwin. The trio posed for a bad-ass pic with the plastic toys Wednesday morning (December 17), looking prepared for battle.

For a year, rumors have been circulating about the Biebs' involvement with Kendall and sister Kylie. Ex-girlfriend Selena Gomez notoriously unfollowed the Jenner sisters from Instagram during one of Jelena's many breakups. But as Bieber now assures fans, "I'm super single... you would know otherwise."

Hailey has been a longtime BFF of the Jenner sisters and model friend Gigi Hadid, so much so that when they visit each other, they accidentally wear similar outfits. "twinning and we didn't even have to try," Kendall wrote along with this photo of the two:

Kylie even stopped in on the fun, copping a hug with nerf-toting Baldwin.

Now, carry on with your nostalgia, Bieber. That's what friends are for!
