Honorable Mention: Satyana Denisof
Alyson Hannigan and Alexis Denisof's adorable little girl has had some majorly cute moments this year, from her contemplative trip down the slide to her awesome bee costume to this snapshot of her conquering the monkey bars with a little help from mommy at an L.A. park. Awww.
10. Shiloh Jolie-Pitt
As long as she's got her toys and her Kanye-style glasses, the world is Shiloh's playground, wherever this brood of eight chooses to travel. (In this case, the exuberant kiddo is leaving LAX with mom and sis Zahara, not pictured.)
9. Mason Disick
This fashionable little guy—who steals the spotlight in every Keeping Up With the Kardashians scene he appears in—knows the best part about any party is the dessert table. Oreo cookies = yum!
8. Naleigh Kelley
Who's the cutest little princess in all the land? It's Katherine Heigl and Josh Kelley's cherubic 3-year-old, all dressed up for Halloween in her Cinderella outfit, complete with glass slippers, a white stole, a crown and even butterfly face paint—to set herself apart from the other Disney princess costumes, natch.
7. Violet Affleck
While pregnant mom Jennifer Garner and dad Ben Affleck share a tender moment during a stroll in L.A., that "Look, I give up on these two" expression on their 6-year-old daughter's face is absolutely priceless.
6. Willow Hart
The huge grin—and over the shoulder, too—of Pink and Carey Hart's newborn baby is too awww-inducing to ignore. We just wanna squeeze those chubby pink cheeks!
5. Zuma Rossdale
Getting a manicure and pedicure to match his too-precious Captain America costume on his birthday? Yep, just another day for the youngest son of rock royalty Gwen Stefani and Gavin Rossdale.
4. Suri Cruise
Hollywood's chicest mini fashionista was snapped this summer looking like a stylish kid about town, running around New York City in her red dress, gold kiddie "high" heels, purple purse and a toy, natch. That's the way Suri rolls.
3. Samuel Schreiber
That expression of pure joy on Liev Schreiber and Naomi Watts' little one's face as he and daddy take off for a bike ride this summer in New York City is so perfect. Being a kid is all about having fun, right?
2. Flynn Bloom
Ta-daaa, Miranda Kerr and Orlando Bloom's little munchkin seems to saying, as if he lifted mommy's leopard blanket off of him to surprise the world with his insane cuteness.
1. Nahla Aubrey
While mom Halle Berry hobbled alongside with a broken foot, her adorable daughter (with ex Gabriel Aubry) shared a playfully tender moment with the star's boyfriend Olivier Martinez in Spain this summer. It doesn't get any cuter than this!
