Congratulations to Melissa Rycroft and Tye Strickland.

The Bachelor alum, 33, and her husband, 34, welcomed their third child – son Cayson Jack Strickland – on Wednesday (May 18), E! News reports.

The newborn – who weighed in at 8 lbs., 12 oz. – joins sister Ava Grace, 5, and brother Beckett Thomas, 2.

In November, the former Dancing with the Stars champ announced her pregnancy news on social media with a photo featuring their kids holding signs reading “Big Brother” and “And then there were five.”

“This is definitely the last one … probably…” Rycroft captioned the family photo.

Congratulations to the Rycroft-Strickland family!
