Los Angeles, California - Kendall Jenner and Jacob Elordi had another double date – this time joining Justin and Hailey Bieber!

The A-listers had a memorable Memorial Day weekend with the supermodel's longtime friends, per new snaps shared by DeuxMoi.

Kendall and Jacob were joined by Justin and Hailey in Montecito, along with a group of "around 12 people total."

An eyewitness said that the Euphoria alum and The Kardashians star "had their backs to us the whole time," and it only clicked once Hailey called out to Kendall by name while the group was leaving.
