It's a mutual admiration society for Taylor Swift and Ciara as the latter and boyfriend Russell Wilson joined the "Bad Blood" singer's squad on stage for her 1989 World Tour concert over the weekend.

E! News reported that Taylor Swift invited Ciara up on the stage while she was performing "Style."

Ciara did come up, but later she was joined by boyfriend Russell Wilson, the quarterback for the Seattle Seahawks.

CBS beat writer John Breech posted a Vine video on his Twitter showing the NFL player and "Love Sex and Magic" singer dancing to Taylor Swift's song. He wrote, "Not saying Russell Wilson can't dance, but he probably shouldn't quit his day job. #Seahawkshttps://cbsprt.co/1MW9PZM."

Ciara also tweeted her appreciation for Taylor Swift for inviting her and boyfriend Russell Wilson on the concert stage. She wrote, "@taylorswift13 You're Truly Awesome! @DangeRussWilson And I Had Fun Rocking With You On Stage Tonight. Keep Shining! You Rock. (heart emoji)️"

The singer's fan wrote, "Future be pissed lol Ciara hot doe Russell Wilson lucky as hell," referring to Ciara's rapper ex.

Ciara and boyfriend Russell Wilson started dating right after she split from rapper Future, with whom he has a son named Future Jr.

One fan noted, "As a die hard #pats fan it's hard to root for anything #Seahawks related but you two make the legit cutest couple."

Taylor Swift reciprocated the gesture by also giving Ciara a shoutout in her own Twitter. Calvin Harris' girlfriend wrote, "That Seattle crowd went ABSOLUTELY INSANE when @Ciara and @DangeRussWilson walked out!! I LOVED TONIGHT."

One fan commented, "Ciara, I'm glad that you have a man that compliments you!!!! @taylorswift13 @ciara @DangeRussWilson."

Another of her fan gushed, "BEST surprise ever!!! One of the many highlights of the show! #goseattle #1989TourSeattle."

"@taylorswift13 @ciara @DangeRussWilson That this unexpected encounter for fans born a new Ciara friendship is a good person," one of her fans added.
