The McCartney family came together to support Stella at her Paris Fashion Week presentation on Monday.
Stella's younger brother James McCartney made a rare public appearance at Parc André Citroën to see his sibling's new collection.
The 46-year-old musician looked dapper in a crisp white shirt and black geometric pattern blazer, which he paired with fitted gray trousers.
At his side was 81-year-old patriarch Paul McCartney, who looked in good spirits as he chatted with his FROW colleagues Paris Jackson and his Beatles bandmate Ringo Starr.
After the show, 52-year-old Stella McCartney walked the runway to thunderous applause and beamed at her family as she strolled by.

After largely avoiding the limelight and even working as a waiter in Brighton, James later followed in his father's musical footsteps.
He spent his first two and a half years touring with his parents as they toured with their group Wings.
He later played guitar on Sir Paul's Flaming Pie and Driving Rain records, as well as The Light Comes From Within – a track he recorded with his mother before she died of breast cancer in 1998.
In 2010, he released his debut single “Available Light” before releasing his first album “Me” in 2013 and his second album “The Blackberry Train” in 2016 – both co-produced by his father.
He had previously said that his goal was to be “better than the Beatles.”
“When I reached a certain age, I realized that I was slightly better at playing the guitar than other kids at school, and I was proud and enjoyed it,” he told the BBC in 2012.
“Back then I dreamed of being better than the Beatles.” I'm not sure I can do that. If anything, I’d like to be the Beatles’ equal – but even that’s pretty difficult.”
He also revealed he is considering forming a group with the Fab Four's descendants, including Ringo Starr's son Jason, 54, Lennon's youngest son Sean, 46, and George Harrison's only son Dhani, 43.
In addition to James, Paul is also the father of three other daughters with his late wife Linda – Heather McCartney, Mary McCartney and Stella McCartney.
The rocker then welcomed 19-year-old daughter Beatrice with Heather Mills, to whom he was married from 2002 to 2008.
Paul has been happily married to Nancy since 2011.

Paris and Paul sat down with Sir Ringo and his wife Barbara Bach four decades after his huge feud with their King of Pop father Michael to prove there was no bad blood

Paul and Michael fell out after he bought the rights to the Lennon and McCartney catalog from under McCartney's nose for $47.5 million (pictured with Linda McCartney in 1983).
Stars were out in force at Stella's show, with Paris Jackson one of the stylish attendees who wowed in a bodycon tiger print dress.
The 25-year-old model and actress looked amazing in the high-neck dress, which she paired with brown strappy heels and a chic clutch bag.
Paul previously had a feud with the late Michael Jackson in 1985, which remained unresolved until the King of Pop's death in June 2009.
But that didn't stop the Beatles frontman from sitting next to Michael's daughter at the show.
Paris was sandwiched between Paul and his Beatles bandmate Ringo, who was there with his wife Barbara Bach, 76.
Paul and Michael used to be friends and worked together on a song called “The Girl Is Mine” – a track that Macca was never really keen on and which appeared on the Thriller album.
It was their second collaboration, having recorded “Say, Say, Say and The Man” the previous fall, which appeared on McCartney's album “Pipes of Peace” in October 1983.
However, they fell out when Michael asked Paul for advice on how to protect his assets and Paul advised him to invest in music publishing.
Michael then bought the rights to the Lennon and McCartney catalog from under McCartney's nose for $47.5 million and they never spoke to each other again.
Paul said at the time: “I think it's dodgy to do something like that.” “Be friends with someone and then buy the carpet they're sitting on.”
