The NBC comedy's showrunner Ryan Murphy broke the news on Twitter on Wednesday evening (October 10).
"Guess who's coming on The New Normal as Bryan's sexy ex-boyfriend? The one and only Matt Bomer!!!" Murphy wrote.
The White Collar actor also made a guest appearance during the third season of Murphy's comedy Glee, playing Blaine's older brother Cooper.
Bomer duetted on a rendition of Gotye and Kimbra's 'Somebody That I Used To Know' with Darren Criss on the Fox show.
The New Normal stars Andrew Rannells (The Book of Mormon) and Justin Bartha (The Hangover) as a successful couple who decide to have a baby with the help of surrogate Goldie (Georgia King).
