Picture perfect!

Bachelor alum, Melissa Rycroft and husband Tye Strickland welcomed a baby boy, Cayson Jack, two days ago — and the proud mama has already taken to Instagram to share an adorable photo of her daughter, Ava Grace, 5, meeting her newborn brother for the very first time.

The former DWTS contestant, 33, captioned the sweet moment, "Their first 'hello.'"

Cayson Jack is cleverly pictured wearing a Dallas Cowboys hat, which could be the work of his proud mom who is a Texas native and former Cowboys cheerleader.

This is the third child for the brunette beauty and her hubby, who are already proud parents to son, Beckett, 2.

We hope the happy family is enjoying their new bundle of joy!
