GIRL OF HONOR

For their daughter's 3rd birthday, dads Bill Horn and Scout Masterson (here with Simone in her personalized purple scrubs) teamed up with pal and party stylist Jenny Keller of Jenny Cookies to create the perfect event based on Disney Jr.'s popular show, Doc McStuffins, at their Los Angeles home on June 1. "Simone loves Doc McStuffins – the cartoon is so colorful and fun. So we loved the idea of using it as the theme," says Horn.

MINI CAFETERIA

Horn and Masterson – a.k.a. the Guncles – used miniature containers from Kara's Party Ideas for their kid-friendly food table, which featured bite-size dishes (Chilly's Chicken bites, Hallie's taters, Stuffy's stuffing balls, Doc's special mac amp cheese) inspired by the show's animated toy characters. The pretty pink-and-white banner was designed via hip online stationery company, Minted.

DOCTOR'S ORDER

Forget yucky medicine! Guests including Lisa Rinna, Beverley Mitchell, Tia Mowry, Jennifer Aspen, Marissa Jaret Winokur and their families enjoyed sweet treats (gumballs, rock candy and more) from vintage-style pharmacy jars. "We created our candy bar inexpensively. We found the jars on Ebay and the colorful candy at Oriental Trading," says Masterson.

PARTY ANIMALS

After changing out of her scrubs into an equally cute white doctor's coat, Simone made sure to spend time with Tori Spelling's daughters, Stella and Hattie McDermott, as the trio show off their face paint.

CHIC REFRESHMENTS

"We wanted to keep the drinks simple and beautiful so we used this work bench we found at our local flea market for $40. We gave it an antique-y feel with gray paint and then dressed it with banners from Minted," shares Horn. "The self-serve station also included mini Mason jars with flower-cut lids and oversize drink dispensers on Rosana cake stands filled with a margarita recipe we found on Pinterest."

YUMMY DISPLAY

To create the ultimate Doc McStuffins dessert table, Horn and Masterson adorned the table with Minted decorations: "Their party kits help transform any party into an elaborate affair." And they added cake stands from Etsy shop A Fabulous Fete, and white crates from Michael's to showcase the amazing cookies (they're shaped like band-aids and thermometers!), cake pops and cupcakes. But it was the giant clipboard from Pottery Barn Kids that really took the station to the next level. "After the party, we're moving it into Simone's bedroom to add a fun design element."

FRIENDS FOREVER

"We can't imagine throwing a birthday party without Jenny. She did Simone's 1st, 2nd and now 3rd birthday," says the couple. "Having her in our home is a family tradition! And we also use her for all of our celebrity family events (Santa's Secret Workshop, Corolle Dolls, etc.). Her talent and creativity are beyond compare." Here, Jenny takes a sweet snapshot with the birthday girl.
