Theresa Gonzalez has a "fresh" new role: The "Challenge" vet is a proud parent!

The "Fresh Meat 2" alum -- who also appeared on "Rivals," "Rivals 2," "Free Agents" and "Battle of the Exes 2" -- welcomed a baby girl Easton Kaia Jones with her fiancé TJ Jones this past weekend. Shortly after the precious princess' arrival, the MTV cast member lovingly introduced her wide-eyed and beautiful daughter to the world.

"I'm here!!!!" the gushing matriarch -- who announced she was expecting right before Mother's Day -- wrote along with the sweet Instagram snapshot above of her alert newborn. "Born December 5th at 6:08 PM, 7 lbs 7.9 oz, 20.5 inches long, our Korean/Hawaiian/Black/Irish/PuertoRican bundle of joy!!" Someone would look mighty cute in a "Challenge" onesie with that stylish hat (just saying).

And before the duo became a family of three, T shared a photograph during the final moments of her pregnancy (seen below) -- appropriately with the caption "Game Time." This mama does know a thing or two about daring missions...

Be sure to offer your congrats to Theresa and TJ on the birth of Baby Easton -- and catch a brand-new episode of "The Challenge: Battle of the Bloodlines" this Wednesday at 10/9c!
