Michelle Monaghan's Favorite Role

The new mom recently spent her first evening away from Willow, leaving her at home along with husband Peter White while she attended the amfAR gala in New York. “I imagine I miss her more than she misses me," she admitted.

Motherhood seems a perfect fit for the Eagle Eye star, who gushed that “every day feels like Christmas” with her baby girl, and added, “It’s such a profound love.”

Michelle, 32, showed off a trim figure at the event, and credits her post-baby weight loss to breastfeeding and her new health-conscious lifestyle.

"Honestly, I started working out after two-and-a-half months," she revealed. "I have a trainer. I've just been lifting weights and breast feeding. And I eat really healthy and a lot, because I'm breast feeding ... always organic. I frequent Whole Foods. I never really cared so much about my diet until I got pregnant and had a baby."
