Nicole Kidman arrived in Sydney, Australia with a big smile on her face and a daughter in each hand and we can't help but wonder how she juggles it all.

Kidman -- who stunned the world with the out of the blue announcement that she and hubby Keith Urban welcomed a baby girl, via a surrogate, in early 2011 -- isn't the only fabulous mommy in Hollywood that literally seems to have it all. She is joined by the likes of Katie Holmes, Jennifer Lopez, Angie Harmon and Heidi Klum, to name few, as well as a whole slew of others who juggle the tough job of being a mom and the fabulous life of a celebrity.
