Sienna Miller flaunts her toned abs in a summery crop top

She never puts a foot wrong when it comes to fashion.

And Sienna Miller looked effortlessly stylish as she attended Deliciously Sorted’s star-studded 20th anniversary party in Ibiza on Monday night. 

The actress, 40, flaunted her toned abs in a summery light pink linen crop top for the night out where she looked in great spirits.  

She teamed the midriff-baring top with high-waisted white jeans that she wore with a red and yellow Boho belt. 

The blonde beauty boosted her height with white leather heeled boots and toted a matching white Prada bag while donning dangling gold earrings. 

Sienna wore her short blonde tresses in loose waves over her shoulders and opted for a natural makeup look to show off her pretty features.

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

The star has chosen her friend Gaby Dellal, 61, who apparently has the ‘best taste’ of anyone Sienna has ‘ever met’, to renovate her Buckinghamshire cottage – despite her stepmother being a world renowned designer.

But while her stepdaughter may prefer to take the advice of others, it appears Kelly, 63, still has fans in high places in the form of Boy George.

The Daily Mail’s Richard Eden reports that after taking one look at Kelly’s £12.5 million mansion, singer Boy George ‘fell in love with it’ and has tasked her with doing up his own gothic-style North London home in the same way.

The Culture Club singer, 61, told Kelly: ‘I want you to redo my house and I want it to look exactly like this.’

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

The actress, who purchased the abode when she was 25, said of her place: ‘It was a time when there was a lot of press attention on me, and I wanted somewhere to escape. I bought the house on a whim-it offers a sanctuary.

‘I also wanted somewhere where family and friends could gather. It has a nurturing feeling; it is a home with a heart.’

And while said family members may include Kelly, Sienna told firmly told the publication that ‘I wanted a Gaby house!’ referring to the director’s homes in London and Cornwall.

Pals: The trio looked in great spirits as they partied the night away in Ibiza together 

While Gaby said of the project, which was completed during the 2020 lockdown: ‘What was beautiful is that she just trusted me, and we had a deal whereby she was not allowed there for six months until I completed 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 step children.

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

‘She calls me Mama K and I call her Sasa. She and Sienna always send me cards and flowers on Mother’s Day, which really touches my heart.’

Meanwhile, Sienna recently enjoyed a getaway in the South of France with her model boyfriend Oli Green.
