At pop icon Diana Ross' 75th birthday party last night, the one and only Beyoncé sang Happy Birthday to the legendary superstar.
Many other celebrities were also in attendance at the Rock and Roll Hall of Famer's bday soirée in Los Angeles, California, including Diddy, Khloe Kardashian, and Robin Thicke.
In the beginning of the video, you can hear Ross' daughter Tracee Ellis Ross asking "Beyoncé, are you still here?" over the mic. Bey walks up with her iconic braid and begins serenading "Ms. Ross."
Twitter had a lot of feelings about the moment.
Legends supporting legends!
