Nick Viall Says He Hopes His Special Forces Experience Will 'Help Toughen Me Up' for Fatherhood (Exclusive)

Nick Viall is thinking about what it's going to take to be a dad for the first time.

In an exclusive clip from an upcoming episode of Special Forces: World’s Toughest Test, the Bachelor alum, 42, opened up about his unlikely participation in the physically and mentally demanding competitive reality show.

"Probably definitely should not be here. There's nothing about what I'm doing now that suggests I'm going to do well in this kind of environment," he acknowledged.

"But I recently found out that I'm going to be a dad, which is incredible. I want to know if it has what it takes to rise to the occasion and I think this experience will shape me and help toughen me up."

The Viall Files podcast host and pregnant fianceé Natalie Joy, 24, shared the sex of their baby on the way in a sweet reveal in September.

Sharing a video of Viall popping a black balloon that released pink confetti and pink balloons throughout the room, he wrapped his arms around Joy, who laughed and leaned into him.

"Baby Viall is a....🤍," Joy captioned her post.

In the comments, Viall joked about what his future daughter's first word might be. "Her first word will be....Boundaries."

The couple, who got engaged in January, first announced their pregnancy news in August.

Sharing a joint carousel of photos to their Instagrams, Viall and Joy posed together with the former Bachelor reaching his arms around and cradling his fianceé's bump. "Our biggest dream came true 🤍," they captioned the post.

The pair spoke to PEOPLE exclusively in August about how Joy told Viall she was pregnant during their daily dinner routine. 

"I took two positive pregnancy tests, got a couple of baby outfits, and put them in a drawer, knowing Nick would open it when we were making dinner," Joy shared. "He was shocked, to say the least."
