ABC's Queen Family Singalong aired on November 4 at 8pm and we are still singing all of the songs. The special was to celebrate the 50th anniversary of the band and was hosted by Darren Criss. The Glee actor closed out the show with the band's biggest hit, "Bohemian Rhapsody."

This is the fourth installment of the singalong series, which started during the pandemic to bring joy to people's lives during the hard time.

Artists such as JoJo Siwa, Adam Lambert, One Republic, Fall Out Boy, Pentatonix, Jimmie Allen and Miss Piggy, among others all performed Queen's biggest hits. But there might have been one duo that you are not too familiar with.

Alongside Dancing With The Stars six-time champion, Derek Hough and his dancer girlfriend, Hayley Erbert, Alexander Jean delivered a powerful performance of "Another One Bites The Dust." If you are a fan of DWTS, you might have recognized one of the members, but who exactly is the duo of Alexander Jean?

11 Mark Ballas

Mark Ballas is a two-time Dancing With the Stars Champion and has reached the finals many times, earning him an Emmy nomination for his outstanding choreography. Ballas danced for 18 seasons before leaving the show to pursue other things. He has released solo music, been in a band called The Ballas Hough Band and is the son of esteemed dancers Corky and Shirley Ballas. The 35-year-old has also starred on Broadway including Jersey Boys and Kinky Boots. Ballas is married to singer/songwriter BC Jean.

10 BC Jean

Brittany Jean Carlson, known professionally as BC Jean, is an American singer and actress. She is best known for writing the song "If I Were A Boy," which was later recorded by Beyonce and reached commercial success. Before meeting Ballas, BC released solo music, with her first single "Just A Guy," being released in 2010. She also starred in the web series, Talent. Now, the 34-year-old lives in Los Angeles with Mark and their dog, Hendrix.

9 How They Met

Ballas talked to InStyle magazine about how him and BC met back in 2016. "A few years ago, a mutual friend of ours hosted an online concert where people could buy tickets that donated to charity, and both BC and I were on the bill. When I arrived, It was so packed that you literally could not move. BC was on stage, and I couldn’t see her—I could only hear her. I remember thinking, 'Wow. She’s got it going on.' She sounded like a mix of Janis Joplin and Stevie Nicks. I was expecting to see someone in their forties slugging whiskey, but I was in complete disbelief when the crowd cleared and I saw a gorgeous blonde." And the rest was history.

Jean also told her side of the story. "When Mark took the stage, my immediate thought was that he's super talented. He was doing a lot of hip thrusts and started flirting with me, but I was all about the business. I wanted to make sure that we could work together. Five and a half hours later, we were on a date, and we've been together ever since."
