The party comes after reports that Sienna snubbed the services of stepmother Kelly Hoppen’s interior design firm and instead asked a friend of the film director to decorate her cottage.

The star has girlfriend Gaby Dellal, 61, who appears to have the “best taste” of anyone Sienna “ever met” to refurbish her Buckinghamshire cottage – despite her stepmother being a world-renowned designer.

But while her stepdaughter prefers to take advice from others, Kelly, 63, seems to still have fans in high places in the form of Boy George.

The Chron’s Richard Eden reports that singer Boy George “fell in love with her” after seeing Kelly’s £12.5million mansion and commissioned her to furnish his own Gothic-style home in north London in the same way .

The 61-year-old Culture Club singer told Kelly, “I want you to renovate my house and I want it to look exactly like it.”

Meanwhile, Sienna recently featured her newly renovated thatched 16th-century cottage in the Buckinghamshire countryside in the latest Architectural Digest.

The actress, who bought the apartment at the age of 25, said of her apartment: “It was a time when a lot of press attention was focused on me and I wanted to escape somewhere. I bought the house on a whim – it offers a sanctuary.

“I also wanted a place where family and friends could meet. It has a nourishing feel; it is a home with a heart.”

And while family members might include Kelly, Sienna emphatically told the publication, “I wanted a Gaby house!” Referring to the director’s homes in London and Cornwall.

Whilst Gaby said of the project which was completed during the 2020 lockdown: “The nice thing was that she just trusted me and we had a deal where she wasn’t allowed to be there for six months until I finished the project.”

Kelly married Sienna’s investment banker father Ed Miller in 1989 when the actress was just six years old and her sister Savannah, seven.

Despite divorcing Ed in 2003, the entrepreneur has remained close to her former stepchildren.

Speaking about her relationship with Savannah and Sienna in Mail on Sunday magazine in 2020, Kelly said: “You [Savannah] and her (actress) sister Sienna are and will always be two of the most precious people in my life – even though I’ve been divorced from her father Edwin for 17 years.

“She calls me Mama K and I call her Sasa. She and Sienna always send me cards and flowers for Mother’s Day, which touches me deeply.”

Meanwhile, Sienna recently enjoyed a getaway to the south of France with model boyfriend Oli Green.
