'Challenge' Champ Paula Beckert Welcomes A Mini-Walnut

Meet the MTV cast member's baby girl!

Make way for a future "Battle of the Bloodlines" duo: Paula Beckert is now a proud parent of two!

The "Rivals" and "Rivals 2" winner -- who is mom to son Atlas with her husband Jack -- kept the Greek mythology trend going with the moniker choice for her daughter, who is named Athena Rose. And fortunately for fans of the "Challenge" all-star (lovingly nicknamed Paula Walnuts), the birth announcement featured a precious video of the tiny nut during her early hours of life on Mount Olympus with her loving folks.

And before the little lady made her highly anticipated debut on D-day, Paula made sure to snap a photograph with her husband outside of the hospital. You're glowing, P!

Be sure to offer your congratulatory messages for Paula and her family in the comments -- and for a taste of what's to come during this season of "The Challenge," watch the action-packed "Battle of the Bloodlines" trailer below!
