Make way for a future "Challenge" all-star: Katie Cooley (formerly Doyle) just had a bouncing baby!

The MTV alum -- who made her debut on "Road Rules: The Quest" back in 2001 (MEMORIES) and subsequently appeared on "The Gauntlet, "The Inferno," "Battle of the Sexes 2," "The Gauntlet 2," "Fresh Meat," "The Gauntlet 3," "The Duel 2," "The Ruins," and "Cutthroat" -- welcomed her first child with husband Cory Cooley. Time to outfit this kiddo in a "Challenge" onesie ASAP...

"Introducing Avery Ryan Cooley!" the no-holds-barred competitor -- who shared her pregnancy news back in November with a clever movie-themed announcement -- tweeted along with this scrumptious snapshot of her darling newborn. Wonder if the Texan's mini-me will inherit her mama's feisty personality and penchant for always speaking her mind -- or the ability to really throw down in an elimination round. Time will certainly tell!

Be sure to offer your congrats to the new family in the comments -- and for a trip back to the ol' days, watch Katie have a memorable, profanity-laced meltdown:
