'The Challenge's Paula Beckert Gives Birth & Her Former Castmates Adorably React on Twitter

Exciting news, Challenge fans! Paula Beckert of The Real World: Key West has lots to be celebrate, and it has nothing to do with winning a big fat check from TJ Lavin. On Saturday, Paula Beckert gave birth to a healthy baby boy Atlas. This is Paula's first child and she simply announced his arrival with a tweet, "#imamommy." She's also not the only Challenge vet with big baby news. Robin Hibbard-Coulter of The Real Word:San Diego announced her pregnancy just last week. Robin, who is welcoming her second child posted a photo online of her ultrasound with the caption, "I guess I'm not getting the challenge call for next season lol, it's all good I've got a huge challenge ahead."

Though Paula won't be returning to The Challenge arenas any time soon, she's still getting plenty of attention from her former castmates. Oodles of Challenge alumni have tweeted their congratulations to the happy new mom. Dunbar, who appeared on Battle of the Exes with Paula even sent out a cheeky joke, which was of course in nothing but good taste considering Paula was happily married this past April.

Sometimes the world of The Challenge seems like a non-stop drama-fest, but it turns out in real life, these cast mates really do care about each other. Let's take a look at how Challenge stars reacted to the happy news!
