Diana Ross sings ‘Happy Birthday’ to Beyonce during Los Angeles stop

It was a present fit for a Queen.

Beyoncé was left speechless Monday after music legend Diana Ross stopped by her star-studded Renaissance Tour to sing “Happy Birthday” to the “Partition” singer.

The Motown legend, who made her grand appearance at the end of the show, stepped out wearing a shimmering black dress complete with feather cuffs causing the 70,000-plus crowd to go “upside down” with delight, according to a TikTok.

Rumors that the “Love Hangover” songstress might appear had been circulating for weeks since Knowles-Carter, 42, sang at Ross’, 79, birthday in 2019.

The Post has reached out to Beyoncé and Ross for comment.

In the video, which was posted early Tuesday morning, Beyoncé can be seen looking “Crazy in Love” as Ross and fans belt out the tune.

Following the emotional moment, both singers embraced as Beyoncé offered her sincerest thanks.

“Thank you so much, you are so amazing,” gushed the singer. “This is the legendary Diana Ross! There would be no me without you and thank you so much for all of your sacrifice and your beauty and your grace.”

“Thank you for opening doors for me. Thank you so much,” continued the “Break My Soul” singer.

Ross then replied that she was returning the favor.

“You sang Happy Birthday to me so I wanted to sing it to you,” replied Ross, who was smiling warmly at her friend.

Back in 2006, the “Single Ladies” icon told Entertainment Weekly that Ross influenced many of her songs as well as being the inspiration to join the cast of the 2006 musical film “Dreamgirls.”

“She’s an all-around entertainer: a great actor, a good singer, and a beautiful, elegant woman,” said Beyoncé. “She’s one of the few singers able to cross over into really good movies.”

The sweet moment was captured by several fans including reality star Kim Kardashian who attended the concert along with her family.

Kardashian, 42, was not the only A-lister to join in Queen Bey’s birthday celebrations.

Pop icon Katy Perry also attended the festivities donning an all-silver outfit — per Beyoncé’s instructions — as well as “Spiderman” star Tom Holland and his long-time beau Zendaya.

On Friday, Meghan Markle and Prince Harry paid their respects to the Queen by attending the pre-birthday bash concert.

Though Markle seemed to be getting in “formation,” Harry was dragged on social media for looking “bored.”
