Turning 40 on December 28, the singer and father-of-two celebrated his birthday milestone in the most excessive and glamorous way possible over the weekend.

Alongside his wife Chrissy Teigen, John was joined by Kim Kardashian, Kanye West, Kris Jenner, Kourtney Kardashian among other friends at the over-the-top event.

Since the big night, Kim has shared someCasino Royale-esque photos from the event on Twitter and Instagram.

Prior to the party, Chrissy asked her fans which tuxedo the couple's seven-month-old son Miles should wear to the party.

"Okay guys. Throwing John's 40th birthday party tonight but need your help dressing mini-John. Which one!" she wrote.
