The 66-year-old's son, Burt Jenner, and his girlfriend, Valerie, are expecting their first child together and made the announcement on Instagram yesterday, with this ultrasound photo.
"I promised to wait until we had the "all healthy" update , and we got it yesterday... 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," he captioned the pic.
Valerie also shared the photo on her page, along with the caption "Oh boy!" and an absolutely adorable emoji trio - a Christmas tree, a gift and a little baby chicken hatching out of an egg.
So exciting! Cait just had another grandchild a few days ago [Kim Kardashian and Kanye West's son, Saint] and now she has another one on the way!
Huge congrats to Burt and Valerie and congratulations to Cait on having another grandchild!
