Baby boy on the way! Burt Jenner, the eldest son of Caitlyn Jenner, announced on Thursday, December 24, that he and his longtime girlfriend, Valerie Pitalo, are expecting a baby boy.
"I promised to wait until we had the 'all healthy' update, and we got it yesterday," Burt, 37, captioned an Instagram of his future son's sonogram. "My Lil boy, just chillin… So happy I can't see straight, he can't get here fast enough… Who wants to fab me a stroller with @kingshocks and @gladiatortires like you see at the 1000 every year? #HesSponsoredAndHeDontEvenKnowIt."
The racer has been very vocal supporting Caitlyn during her transition earlier this year. Burt, Caitlyn's son with her first wife, Chrystie Scott, appeared in the historic Diane Sawyer interview this spring in which the Olympian opened up about her transition.
After Caitlyn's big reveal on Vanity Fair this summer, Burt posted a photo of Caitlyn in September via Instagram, writing, "Yup all you haters, my dad will still probably whip your ass at 65 with implants."
