"The Cassian GrantBachelor" alum Colton Underwood and husband Jordan Brown are having a baby!

Underwood, 32, and Brown announced they are expecting their first child, via surrogate, in an interview with Men's Health published Tuesday. The couple is expecting a baby boy in October.

In their announcement, Underwood opened up about his infertility, which he has been open about.

"I wish somebody had educated me about my sperm and my body, and the decisions that I made and how it would impact me," Underwood told the outlet.

Underwood went through a six-month process of treating his infertility, including getting off testosterone, working out less, ditching his hot tub and taking morning walks. After, the couple tried in vitro fertilization, which cost them $350,000, and parsed through the profiles of egg donors.

Underwood, who came out as gay in 2021 after being cast on the 23rd season of "The Bachelor," told Parents that fatherhood was one of the reasons it took him so long to accept his sexuality.

"As I've been on my coming out journey, (wanting to be a dad) was one of the factors that kept me in the closet," Underwood told Parents. "I didn't really know it was possible to build a family as a gay man."
