Like many new parents, Fergie and Josh Duhamel are commemorating their first holiday season with son Axl with an unforgettably adorable Christmas card. Fergie, 38, dutifully shared the card with her 2.8 million fans on Twitter presumably not on the couple's holiday card mailing list.

"Have a Jolly Holiday!" the "Glamorous" singer wrote in the caption. In the photo, Axl, 3 months, smiles sweetly in a casual framed portrait. Fergie and Duhamel, 41, celebrated their fourth wedding anniversary back in September. Little Axl was baptized earlier this month in L.A.'s Brentwood nabe.

The actor and singer are definitely ready to give Axl a little brother or sister. "We've gotta move fast! [Axl's] a really good little baby, which means the second one will be a holy terror!" he joked.

Fergie got emotional speaking with Ellen DeGeneres in November about Axl's C-section delivery. "It was really special. It was very special . . I see Josh's face. They're pulling Axl out. I can't feel anything. I'm all numb. And I see Josh, and he's going, 'Aw,' and he's giving the faces, and I'm going, 'Wow, I'm so happy. This moment is so special, so tender...'"
