And baby makes five! Bachelor alum Melissa Rycroft welcomed her third child — a boy — with husband Tye Strickland in Dallas on Wednesday, May 18, Us Weekly can confirm.

The Dancing With the Stars All-Stars champ and her husband have named the 8-pound 12-ounce newborn Cayson Jack, her rep tells Us, and he joins big sister Ava Grace, 5, and brother Beckett Thomas, 2.

The 33-year-old announced that she was expecting baby No. 3 in November, sharing the good news on Instagram along with a family photo. "This is definitely the last one…probably…" she wrote. "#partyoffive #babyonboard #maybethisonewilllooklikeme."

The couple had been enjoying watching their two older children bond prior to the arrival of Cayson. "They're starting to form a relationship, it's cute," the former Dallas Cowboys cheerleader told Us Weekly last year. "They'll go into the playroom and I'll just hear Ava talking to [Beckett] and they're kind of in their own make-believe world. It's fun."

Rycroft — who won the heart of Jason Mesnick on season 13 of The Bachelor in 2009, only to have him dump her during the live taping of the After the Final Rose special for runner-up Molly Malaney — married insurance agent Strickland in December 2009 after a six-month engagement. 

E! was the first to report the news of Cayson's arrival.
