It was a star-studded affair at Diana Ross’ 75th birthday extravaganza, as the Motown legend celebrated in style with some of the most notable names of the entertainment industry.

The party started at the famed Hollywood club Warwick, before later moving over to the Hollywood Palladium, where the Supremes icon was joined by her family as well as the likes of Diddy, DJ Khalid, Robin Thicke, French Montana, Kris Jenner, and Kourtney and Khloe Kardashian to name a few.  With that said, per usual nobody could upstage Beyoncé as she was chosen by Ross to sing her an impromptu version of “Happy Birthday’ around what was dubbed “the biggest cake ever,” and as expected, the Dreamgirls actress delivered a flawless rendition that led to a loving embrace between the two iconic stars.

It should be noted that this isn’t the first time Beyoncé has serenaded the singer, as back in 2000 she covered the 1980 disco hit “Upside Down” with Destiny’s Child for a tribute concert dedicated to Ross’ illustrious career.
