New mom Megan Fox is going all out to celebrate newborn sonNoah Shannon's very first Christmas. Among the ways she's decking the halls at home? She and Noah are grooving to some festive holiday tunes.

"I like Michael Buble's Christmas album -- I know that's cheesy," Brian Austin Green**'s wife, 26, told Us Weekly at a press junket for her new film This Is 40. "My baby likes him too so we're into that -- he's a smooth crooner."

Welcoming her son in late September, Fox has called motherhood "overwhelming," but tells E! News she can't get enough of her son's latest milestones. "He's getting to that place where he's smiling and he's almost ready to laugh, and I can't wait for that baby laugh that almost makes you feel like you can fly, like your heart's going to explode," says Fox, who also helps raise Green's son, Kassius, 10, from a prior relationship with actress Vanessa Marcil.

Appearing in This Is 40 opposite Leslie Mann and Paul Rudd**, Fox admits motherhood has also heavily impacted her career, given that she now more carefully considers the roles she intends to take on. "It changes your perspective about being overly sexual in a film when you have a baby," the actress recently told the U.K.'s Mirror.

"I'm going to be more cautious about choosing films because I'm already thinking about when he's in school and his friends are going to be showing him my photo shoots with me in a bikini and he's going to be horrified."
