Jason Bateman
We're not really sure who's cuter, Francesca or the Arrested Development star. Either way, that little one is traveling in style!
Hugh Jackman
Whether bike riding, eating ice cream or dressing as Snow White, the star's daughter, Ava, is always beaming when she's photographed with her pleased papa. As a matter of fact, so is older brother Oscar (not pictured).
Sean "Diddy" Combs
If the mogul's parenting skills are anything like his twittering, it's safe to say this dear ol' dad is loud, positive and a total blast.
Christian Bale
We have a feeling Batman keeps the expletives to himself when he's spending quality time with daughter Emmaline.
Mark Wahlberg
The actor has a funky bunch all his own with longtime love Rhea Durham. With daughter Ella Rae (pictured) and sons Michael and Brendan Joseph, he always has an adorable date to a basketball game.
Tobey Maguire
We wonder if paternal instincts are anything like Spidey sense. If so, his daughter Ruby and newborn son will always be safe in dad's wall-climbing arms.
Anthony Kiedis
Even hard-core rock stars look cute with their kids. The Red Hot Chili Peppers frontman appears to be practically PTA-ready whenever he's seen with son Everly Bear.
Liev Schreiber
The Wolverine star shows his softer side when he appears with son Alexander (called "Sasha") and domestic partner Naomi Watts. The couple welcomed a new addition to their family this past December with the birth of Samuel Kai.
Will Smith
Jaden and Willow (not pictured) are lucky to have such an action-packed dad backing them up. The star, along with wife Jada Pinkett-Smith, manages to be quite the family man, actor-producer and overall nice guy seemingly at all times.
Matthew McConaughey
It's only a matter of time before the beachy-keen star starts sharing his surfing secrets with tot Levi.
Gavin Rossdale
The rocker dad always looks like he's having a ball when hanging out with his mini-me, Kingston, baby Zuma and wife Gwen Stefani.
Adam Sandler
The funnyman puts his gross-out humor on hold when spending time with Sadie Madison, 3, and Sunny Madeline, 7 months.
