Divas respect divas! Beyoncé serenaded Diana Ross on Tuesday night with a flawless performance of "Happy Birthday" at the Motown legend's 75th birthday party in L.A.
Video shot by Khloe Kardashian shows Ross' daughter, Blackish star Tracee Ellis Ross, asking Bey to sing. "Beyoncé, are you still here? Do you want to sing 'Happy Birthday?'" Tracee asks into a microphone.
"Come on down. We're all huddled up around the biggest birthday cake ever."
As Tracee and Diana wait for Bey, Robin Thicke sidles up to Diana and jokes, "We'll take Beyoncé over me any day." Bey then sings while such celebs as Diddy and Ross' son and Ashlee Simpson's husband Evan Ross look on.
The clip ends with Diana taking the mic and declaring, "Thank you, thank you, thank you all! I am so blessed to have so many people here with me. I love you so much."
