Beyonce not only wound down the last of her three Renaissance Tour stops in Los Angeles on Monday, but also celebrated her 42nd birthday… with a special surprise guest taking the stage to sing Happy Birthday to her: Diana Ross.

The crowd stunned when the 79-year-old diva took to the stage during the evening, in a glamorous glittering black gown.

She helped lead the crowd in singing Happy Birthday at just after 11 PM, hours after rumours surfaced that she would make a surprise appearance.

Just like the first two concerts in L.A. over the weekend, the crowd was filled with celebrities, like Kylie Jenner and Timothee Chalamet, seemingly going public with their romance after month of rumors that they have been dating.

Other celebs in attendance included Adele, Zendaya, Tom Holland, Kate Hudson, Justin and Hailey Bieber, Chris Rock, Lizzo, Katy Perry, Kate Hudson, Normani, Brandy, Kim and Khloé Kardashian, and many more.

Ross came out to sing her song Love Hangover, before wishing Queen Bey a happy birthday, with Bey rushing up to give her a hug with tears in her eyes.

‘I’m here to celebrate Beyoncé’s birthday,’ Ross said, as Bey was seen mouthing, ‘I love you,’ to Ross.

She lead the crowd in a rousing rendition of Happy Birthday, and after the song they embraced again, as Ross is heard asking, ‘Were you surprised?’

Joining a slew of other A-listers at the 70,000-plus capacity crowd, she layered over a long glittering jacket and accessorised with futuristic sunglasses

‘Thank you so much! You are so amazing! This is the legendary Diana Ross!’ Beyonce said as the crowd cheered for both living legends.

After performing Flaws and All, she delivered a passionate birthday speech, thanking the fans, her family and the original members of her group Destiny’s Child.

‘My soul is full. I’m so thankful, I’m trying not to cry. I’m thankful to be alive. I’m thankful to be on stage. I’m thankful to look out and see your faces,’ she began.

‘I’m thankful to be able to provide a safe space for all of y’all. I’m thankful for music, for the ability to heal myself through music which then heals all of you,’ she added.

She went on to thank her parents Tina and Matthew Knowles and her husband Jay-Z, even referencing her hit 2016 album Lemonade.
