America's Got Talent judge Howie Mandel announced the news on Sunday night with a tweet.
Banks then confirmed, tweeting "TyTy is the new host of #AGT."
"Since I was a little girl, I've been obsessed with grandiose acts and performers who make the seemingly impossible possible. I love how AGT brings that feeling into everyone's home, capturing the best of people who come out and give it their all to make those big, fierce and outrageous dreams come true," Banks said in a statement. "I look forward to connecting with the dreamers, having fun and giving hugs and words of encouragement when needed. And maybe I'll get one or two performers to smize for the audience!"
America's Got Talent returns this summer.
