Happy 1st Birthday Simone Lynn Masterson-Horn!

Happy Birthday Simone Lynn Masterson-Horn! The adorable tot, whom is lovingly referred to as "Nuggy" by her dads 'The Guncles' - Scout Masterson and Bill Horn - celebrated her first birthday in style at The Carousel at Santa Monica Pier.

Thanks to BFF Tori Spelling who helped plan the party, it was a day to remember! Joined by 60 friends and family, including godmother Spelling and her family, Ali Landry and Sasha Alexander, Simone enjoyed a raspberry and pink “Modern Circus” themed bash. “Simone’s birthday was perfect – good friends, family, lots of fun on the carousal, and of course, cake," her dads tell Celebrity Baby Scoop. "Who doesn’t love birthday cake?! Simone’s now a BIG fan.”

The guests noshed on goodies from Grilled Cheese Patrol, Jenny Cookies and Sweet Lucie’s Organic Ice Cream Truck. The flowers were provided by The Bashful Rose and the invitations were created by Copper Willow Paper Studio. The birthday girl wore a dress by Luna Luna and treated her guests to gift bags from Gotta Have It.

Although Simone's milestone birthday is today (June 7), the Masterson-Horns celebrated on Sunday (May 29). So why the early party? "We wanted to space it out from her cousin Stella McDermott’s 3rd birthday party - Stella was born on June 9th," Bill says.

Simone’s party will be featured on Tori & Dean: Home Sweet Hollywood Season 6, set to air later this year on Oxygen. When the show airs, the Masterson-Horn clan will become reality TV’s first gay family to appear on a regular basis.
