Queens unite! Madonna and Beyonce pose backstage at Renaissance show

Pop music royalties reunited backstage at Beyonce’s Renaissance concert on Tuesday.

Madonna attended the New Jersey show with her daughters Mercy, 17, whom she shares with James Kambewa, and adopted twin girls Stella and Estere, 10, and wasn’t left disappointed.

Taking to Instagram Stories, the Material Girl singer posted photos from the concert, along with a backstage photo of Beyonce and her 6-year-old daughter Rumi.

"Thank You Queen B. for your magnificent show!" Madonna wrote on her Story accompanied by a picture of her view on the stage, as the words "Queen Mother Madonna" lit up on the big screen.

Follow-up stories of the singer featured whimsical selfies with her kids. 

Madonna echoed the concert’s energetic spirits with her attire; a multi-coloured co-ord comprised of patterned pink and blue jackets and shorts.

The Holiday singer paired the outfit with black fishnet tights, a fitting corset, matching combat boots, and a pair of oversized shades.

Her accessories for the night out included dangling earrings and a multi-layered diamond-encrusted chain necklace.

Madonna’s latest outing comes a month after she was admitted to ICU for developing a serious bacterial infection.

In a recent gratitude post, the Like A Virgin singer gushed about having her family by her side through the difficult time, writing, "Love from family and friends is the best Medicine. One month out of the hospital and I can reflect."

"As a Mother you can really get caught up In the needs Of your children and the seemingly endless giving……….. But when the chips were down my children really showed up for me," she wrote on Instagram.

"I saw a side to them I had never seen before. It made all the difference. So did the love and support from my friends," the pop star added.
