Concertgoers, we’ve got even more tour news going into the fall.

Seems former “American Idol” winner Jordin Sparks will replace Ciara as an opener on the second leg of Britney Spears’ Circus tour.

Sparks will join Kristinia DeBarge, Girlicious and One Call on the second leg.

According to MTV.com, Ciara had originally been tapped as an opener but her rep confirmed to Rap-up.com that she will no longer be part of the tour. She could pop up at few show dates (Spears, Sparks and Co. will play Atlanta Sept. 4 [Philips Arena] and Greensboro Sept. 5 [Greensboro Coliseum]).

Details seem to be sketchy as to why Cici’s out and the “No Air” singer is in. But you know I always welcome your conspiracy theories, fam.

Have you heard anything in the rumor mill to shed some light?
