Beyonce sang 'Happy Birthday' to Diana Ross -- and there's video
Musical legend Diana Ross celebrated her 75th birthday party with a big, star-studded bash and live concert in Los Angeles on Tuesday night.
One of the best parts of the night? Beyoncé was there to celebrate and sang the "Ain't No Mountain High Enough" hit maker "Happy Birthday."
In a video posted to Twitter, Ross' daughter, actress Tracee Ellis Ross, can be heard asking, "Beyoncé, are you still here? Do you want to sing 'Happy Birthday?'"
"Come on down!" she adds.
Beyoncé then serenades Ross in front of the packed room. Stars like Diddy, Robin Thicke, Ross' son Evan and other celebrities are featured in the clips.
Ross also performed throughout the night at the concert at the Hollywood Palladium, doing lots of her iconic hits.
She delivered an incredible performance of the classic "Ain't No Mountain High Enough."
And "Why Do Fools Fall in Love."
Artists like Stevie Wonder and Diddy, among others, also joined her onstage for musical numbers.
Diddy's daughters even joined Ross onstage while she performed "Stop! In the Name of Love."
It seemed to be a fittingly fabulous evening for the star.
