Kellie Pickler is going to be all over your TV screen. The singer, whose reality TV show, I Love Kellie Pickler, will premiere on CMT on Sept. 18, has also joined the cast of another new series.

Pickler has been announced as one of the hosts of Knock Knock Live, along with Adrienne Bailon, Ross Mathews, Jordan "Shorty" Johnson and TV and radio personality Chuey Martinez. The show, which will air on the Fox network, is described as "a weekly television event, packed with unpredictable and thrilling surprises, that enlists friends, families, neighbors and celebrities to help grant wishes with one simple knock on the door."

Celebrities including David Beckham, Luke Bryan, Common, Florida Georgia Line, Home Free host Mike Holmes, Lea Michele and Meghan Trainor are already slated to appear on the show, which will be hosted by Ryan Seacrest.

Knock Knock Live isn't Pickler's first time working with Seacrest: He was serving as host of American Idol when she came in sixth place on the fifth season of the reality TV talent show in 2006, and Seacrest is also producing I Love Kellie Pickler.

The North Carolina native recently released a new single, "Feeling Tonight," from her upcoming album, which will be her fifth record.

“I hope that it will be this year’s summer anthem,” Pickler says of the song. “Represent the girls and have fun. It’s sassy and fun.”

Knock Knock Live is set to premiere on July 21 at 9PM ET on Fox. More information, including how to appear on the show, is available on the network's website.
