In August, Sean posed with the boys, hugging them close on the first day of school. Isaiah wore a bright pink polo and had his arm around his dad while Samuel wore a blue button-down shirt and grabbed his dad's hand.

"First day of school for my boys! Handsome and smart, their dad is the total package," he captioned the post.

In April, the pair appeared on an episode of The Most Dramatic Podcast Ever with Chris Harrison and were asked about whether they might want to grow their family in the future. The two laughed as Catherine noted, "He wanted five!"

"Then we had three, and we're like, 'Okay, that was a lot.' Five would be a lot. We could handle five, but we like our little group," she continued.

When Harrison suggested they should have mixed in more girls, Sean noted, "I could have 10 girls. It's the boys who are trouble."

"We kind of had a scare not too long ago where it was like, 'Maybe I'm pregnant?' and she did the pregnancy test, and it was negative. We were both really happy, so we were like, 'I think we have our answer now.' We're probably done with three."

Sean added, "I think I'll make an appointment at the doctor soon."
