Sylvester Stallone’s daughters Sophia and Sistine celebrate sister Scarlet’s 21st birthday

Sylvester Stallone’s daughters Sophia, Sixtine and Scarlet were spotted in New York City on Thursday to celebrate Scarlet’s 21st birthday.

The trio – whose reality TV show was renewed for a second season – showed their close bond when they went to a park for a picnic.

Scarlet’s friend Louis Masquelier-Page, a student-athlete at the University of Miami, joined in the celebration.

The birthday girl was seen holding two flower bouquets while wearing lightly washed overalls with a navy blue sweatshirt draped around her arms.

The blonde beauty led the way with her sisters Sophia, 26, and Sixtine, 24, close behind.

The group took advantage of the sunny weather as they laid a blanket on the lush green grass of Hudson River Park.

Sixtine was casually dressed in low-rise brown cargo pants and a long-sleeved white shirt.

She accessorized with a brown baseball cap worn backwards with her long dark brown hair flowing out underneath.

The ensemble was topped off with a sporty yellow jacket, before stripping it off to get more comfortable.

Sophia was casual and cool in a cropped white T-shirt that exposed her tight midriff.

She topped it off with a pair of loose-fitting, high-waisted black pants and a structured black blazer.

The firstborn daughter of Rocky icon Sylvester and model Jennifer Flavin wore a New York Yankees baseball cap and let her long hair fall out of the back opening.

The ladies all wore dark sunglasses as they enjoyed each other’s company on this special day.

Louis, for his part, looked comfortable in brown sweatpants to match his brown hat.

He added a black T-shirt and stepped out in green and white high-top Nike sneakers.

The foursome lugged several bags and an igloo cooler to carry a blanket and food items to the park.

The ladies were active on their respective Instagram accounts documenting their fun day with their followers.

Sixtine paid tribute to her sister as she uploaded a carousel, writing “she’s 21 today. happy birthday to my BEST friend!!!”

In her image slideshow, Scarlet could be seen jumping for joy, cuddling her beau and enjoying a bottle of champagne.

Scarlet dropped into the comments section to thank her big sister, writing, “couldn’t ask for anything more. I love you.’

And she also shared snapshots on her personal account by simply posting a white heart emoji in the caption.

Sylvester and Jennifer, 54, met in 1988 and married nine years later.

Jennifer has since started her own skin care company and her professional endeavors are an important part of The Family Stallone.

Sophia became known through her father in several social media posts and currently hosts a podcast with her younger sister.

Sixtine has embarked on a modeling career and is following in her father’s footsteps in the film industry.

Scarlet is currently balancing her college education with her role in Tulsa King, which stars the protagonist of the Rambo franchise.

The artist’s longtime friend, Al Pacino, and his former costar Dolph Lundgren, have both made cameo appearances on The Family Stallone.

Sylvester recently spoke about working on the reality series during an interview with Colliderexpressing that he, as well as his loved ones, took a hands-on approach to ensure the show was well produced.

“I’m a huge editing enthusiast, and the family has to go into the editing room so everyone’s on the same page,” he said.

The reality series Paramount+ has been renewed for a second season.

The news was revealed on Thursday morning, just a week after the program broke several streaming platform records.

The show, whose star wrote breakup texts for his daughters to send to their boyfriends in a recent episode, had the most successful launch for an original reality series in Paramount+ history.

The program revolves around the actor’s family life and his children’s entrepreneurial activities.
