Inside John Legend's 40th casino royale birthday

John Legend celebrated his 40th birthday with family and friends Saturday night, with a massive casino-royale themed party, thanks to Chrissy Teigen.

His gorgeous and witty wife (with the help of party planner Lisa Vorce) turned their Beverly Hills Mansion into an epic casino night, bringing out the likes of John's inner circle to celebrate.

The room, fully adorned in red roses and gold casino-esqué accents, was filled with an A-list crowd epic enough to ensure major FOMO. Kim Kardashian arrived in a black totally lace jumpsuit down to the shoes alongside Kanye West, while Kourtney K. was all smiles with BFFs Stephanie Shepard and Simon Huck.

Would it really be a party without a Kardashian-style photo booth? From "Modern Family" star Jesse Tyler Ferguson to Kris Jenner, scroll through the gallery below for the most epic photos of the night.

Chrissy and John's children, Luna and Miles, were also attendance looking cuter than ever. Little Luna Legend stunned in a gold ballerina dress while Miles twinned with his dad in a white tux.

Earlier in the evening, Chrissy took to Twitter to ask her followers to chose between Miles' black or white suit.

"okay guys. throwing john’s 40th birthday party tonight but need your help dressing mini-john. Which one!" she wrote.
