Sean, 35, and Catherine, 33, are getting ready to expand their happy little family!
"The first two have been pretty cool, so why not a third?" Sean captioned a sweet photo of Catherine and their two children on Instagram.
"#PartyofFive," the mom-to-be said below her own Instagram, alongside a few emojis.
As fans know, the couple got married in January 2014 — almost a year after they got engaged on ABC's The Bachelor — and share two children together, Samuel, 2, and Isaiah, 13 months.
“It was a complete surprise and I stared at the wall for a good 24 hours,” Catherine told People of her "emotional" experience when finding out about being pregnant for the third time. “I was like, ‘I just had one of these!’"
“Isaiah was 11 months old when we found out,” she added. “It was a little overwhelming to think about but we wanted a big family. This is just the way it was supposed to happen. So we’re excited.”
