The gang was pictured heading out in West Hollywood to mark Hailey’s marriage to Justin Bieber.

They started the evening with dinner at Ysabel before moving to Delilah nightclub where things started getting more raucous.

Supermodel Kendall looked amazing in a tiny blue minidess, which showed off her long legs.

Hailey, who is already officially married to Justin, wore a white dress complete with veil.

The model, 22, got engaged to Justin, 25, last summer and the couple tied the knot secretly at the New York court house a few months later.

They later decided to throw another bash for close family and friends, which is due to take place soon.

An insider told E!: “Guests will be family and close friends/close church friends only.

“It’s going to be very intimate. They don’t want a huge to-do and want it to be very religion-focused and spiritual.”

Speaking recently about being married, Hailey told Vogue Australia: “Look, marriage is always going to be hard and I think good relationships are the relationships that you put the work into.

“Specifically, I said that when there were a lot of new things. I had never lived with someone before.

“I never had to cohabit with somebody in that way, so I was learning how to share space with someone for the first time. We were trying to bend in each other’s direction and learn what was comfortable.”
