They're pregalicious! Future first-time parents Fergie and Josh Duhamel sported matching baby bumps and bandage dresses during the 26th Annual Kids' Choice Awards at the USC Galen Center in L.A. March 23.

While host Duhamel, 40, padded his belly, the Black Eyed Peas singer -- who, like Megan Fox and Steven Tyler, made a cameo during the show's opening number -- showed off her very real pregnancy curves in the polka dot mini. (For the actual show, Fergie sported a vibrant Mary Katrantzou dress.)

Duhamel shared a picture of their costumes via his official Facebook page and joked, "Have I no shame?" Though Fergie, 37, managed to avoid getting slimed, the Safe Haven actor was doused in green goo after Dwayne Johnson won the award for Best Male Butt Kicker. (Other slimed stars included Pitbull, Dwight Howard, Sandra Bullock, Neil Patrick Harris and Nick Cannon.)

"Had a blast with Josh at the Kids' Choice Awards yesterday," Fergie tweeted March 24. "He killed it."

During a pre-awards interview with the Associated Press, the host said he's ready to rear his firstborn with the multiplatinum singer. "We're completely happy. We're much wiser than we were 10 years ago," he said of life with his wife, whom he married in 2009. "I think we're so strong as a couple and all of those things are really important when you bring a little one into the world."
