Today is a very special day for the Duhamel family!
The proud parents were seen toting their wee one and looking as sharp as can be while stepping foot into the church.
The Black Eyed Peas singer wore an ivory pantsuit while her son wore a traditional all-white christening gown with matching booties.
Meanwhile, Duhamel looked dapper in a suit and tie and even helped his wife out by carrying her black clutch.
It seems as though the new mom and dad are adjusting to life as a family of three.
E! News caught up with the singer at the Wet N Wild and Walgreens event she hosted to benefit amfAR last week where she admitted, "I'm still trying to find my footing."
"I'm still figuring out how to balance it all. I'm kind of walking like this," she told us as she imitated walking on a tightrope. "But I think that's something all new moms can relate to."
The 38-year-old also gushed that her firstborn is beginning to emulate his famous mother by showing off his vocal skills.
"He's starting to try to talk to me and sing with me," Fergie said. "I'll sit there and I'll sing songs to him and he'll just look at me and he'll laugh and he'll try to chime in. He makes these really weird sounds! And I'll just clap like the proud mama I am."
