Beyoncé and Kelly Rowland Danced So in Sync at Janet Jackson's Concert, It's Actually Mesmerizing

Beyoncé, 37, and Kelly Rowland, 38, were proud members of Rhythm Nation on Saturday when they attended Janet Jackson's Metamorphosis Vegas residency. The two former Destiny's Child singers were spotted at MGM Resort's Park Theater enjoying the show and singing along as Janet performed classics, including "What Have You Done For Me Lately."

Bey — who was rocking a long ponytail — appeared to be wearing a light top and skirt. Meanwhile, Kelly sported a dark structured top with a short 'do. A series of videos posted by fan accounts Beyoncé Legion and Beylite2.0 capture Bey and Kelly bobbing their heads to the beat while sitting down. But they couldn't stay seated for long as another clip shows them on their feet, clapping and dancing along.

Beyoncé and Kelly's friendship goes way back, as they've shared a special bond since their Destiny's Child days in the '90s and early 2000s. In April 2018, they even gave fans a much-appreciated reunion on stage during Beyoncé's iconic Coachella set. More recently, Bey posted a heartwarming tribute for Kelly's 38th birthday in February. "I love you Deep Deep," she wrote.

Whether they're acting silly in front of cameras or jamming out to Janet under the radar, it's clear that Beyoncé and Kelly really are practically sisters!
