Paula Beckert Is About To Have Her Very Own 'Challenge' Team

See the MTV alum's burgeoning baby bump!

Paula Beckert is about to have her very own rambunctious -- and tiny -- "Challenge" team of two!

The "Rivals" and "Rivals II" champ -- who is already mom to son Atlas with hubby Jack -- is thisclose to welcoming her very own mini Walnut-me and just shared a sweet snapshot of her third-trimester belly. Forget those anxiety-inducing final missions -- D-day is rapidly approaching for this veteran competitor!

"38 weeks! 2 more to go:) #babygirl #belfie #bigbabybump soon to be a family of 4:) #twoundertwo," the erstwhile "Real World: Key West" cast member -- who joyfully announced that she was expecting baby No. 2 in May -- captioned the Instagram photograph above. Here's hoping her little munchkins aren't "rivals."

Paula's bundle of joy will be the first to join a wave of "Challenge" babies-on-the-way: Theresa Gonzalez, Jasmine Reynaud and Laura Waller are all expecting their first kiddos.

Be sure to offer Paula and her fam your well wishes on their impending adorable arrival -- and stay with MTV News for more updates on the upcoming 27th installment of the long-running game series and the 31st season of the "Real World"!
