Robin Hibbard-Coulter Is Facing An Entirely New 'Challenge': A Baby!

The 'Real Wold' alum shared the exciting news on Twitter -- with a photo of her bun in the oven!

With her losing streak on "The Challenge" a distant memory, Robin Hibbard-Coulter has moved on to better (and smaller) things. Namely, a wee little bun in the oven!

The 2004 "Real World: San Diego" alum announced the news via Twitter late last week with a sonogram photo -- and the cutest caption ever:

That's right -- no more navigating slippery slopes and scaling shipwrecked boats for this married woman, who just finished her first trimester. Luckily, former party girl Robin is no stranger to the twists and turns of mommyhood — she just celebrated her son's fifth birthday, complete with only the best in superhero loot and Transformers toys.

While Robin waits for her bump to finally pop, leave your congrats for her in the comments, along with your best birthday wishes for her first-born kiddo!
