Supportive and proud mom-to-be! Fergie, who is expecting her first child with husband Josh Duhamel, attended the Nickelodeon Kids' Choice Awards at the USC Galen Center in L.A. on March 23 to support her husband, who was hosting the show.

For the first time since announcing her pregnancy in February, Fergie wore a form-fitting ensemble that really showed off her baby bump. The Black Eyed Peas singer, 37, styled a short Mary Katrantzou dress with a fishtank print and yellow Roxane heels.

The parents-to-be posed together for family photo backstage, and Fergie even helped her husband out with a skit during the show.

The 40-year-old host gave a shout-out to his wife by dressing up in a tight polka-dot dress and fake baby bump for an opening singing and dancing act. Fergie, however, showed up in the same outfit and jokingly rolled her eyes at her silly husband.

While sitting in the audience during the show, Fergie's baby bump was admired by fellow singers Katy Perry and Selena Gomez. Fergie smiled for a photo as Perry, 28, and Gomez, 20, grabbed her pregnant belly with a look of shock on their faces.
