Justin looked typically trendy when he stepped out over the weekend in a caramel-hued bomber jacket teamed with jeans from his clothing line Drew, while Chantel wowed in a black crop top and leggings, adding height to her svelte frame in open-toe black heels.

Justin’s wife Hailey, 24, was also there to support him on Saturday, and looked beautiful in a sequined dress in snaps shared on Instagram.

In one, the runway star cosied up to fellow model and best friend Kendall Jenner, who also documented their wild night out on social media.

Kendall, 25, offered her social media followers an insight into the group’s wild night, posting a clip of Justin grooving away while surrounded by friends on a party bus, before sharing a photo of the hit-maker wearing a Phoenix Suns hat – the basketball team her boyfriend Devin Booker plays for.
