Tracee Ellis Ross joins mom Diana Ross onstage for 'Lady Sings the Blues'

LAS VEGAS, Nov. 30 (UPI) -- Legendary singer Diana Ross invited her daughter, Black-ish star Tracee Ellis Ross onstage to perform the Billie Holiday classic, "Lady Sings the Blues."

Tracee shared the epic moment on Facebook on Sunday along with how she felt when her mother called her name while performing inside the Venetian Theater in Las Vegas.

"Last week, my mom, out of nowhere, stopped her show and asked me to come on stage and sing. I think the last time my mom asked me to sing I was 5 or 6 years old," Tracee wrote to her 1.2 million followers. "I swear at first I thought she said Evan (my brother, a singer, who was also there). But then I realized she said my name, and before I could think, I was walking toward the stage!"

"There's something about singing... It's no joke trying to do that as the child of DIANA ROSS, let alone while standing by her side on stage," Tracee continued about how nervous she was. "Plus, when you're nervous, it's hard to hear, it's hard to breathe, and it's hard to be present. These are all important things when you are singing!" she explained. "Anyway, here it is, me stepping on stage with my mom, fighting through so many childhood fears and fantasies."

However the performance turned out great with the Ross family able to deliver a memorable, tear-filled moment that brought the audience to their feet. "It has been ages since I've hidden so deeply in my mother's embrace and it was awesome," Tracee concluded about the experience.

Back in August, Tracee made headlines for playing her mom in a recreation of Diana's "Work That Body" music video.
