Fifi Geldof Splits, Sparks Romance with Jon Paul

has reportedly split from her husband Andrew Roberston and found love with actor, model and fellow  Jon Paul Phillips.

The eldest daughter of  and the late Paul Yates, 43, who wed the sand sculptor in 2016, has returned to using her maiden name on social media. 

In snaps obtained by The Sun Fifi was spotted without her wedding ring as she and  Jon, 46, walked her dog through London's swanky Knightsbridge earlier this week. 

A source told the publication: 'Fifi and JP are very much in love. She has gone through so much pain in her life and it is lovely to see her happy'.

Fifi also reportedly celebrated her 43rd birthday with Jon on Tuesday as he treated her to a £1,300-per-night apartment stay.

She is said to have shared a snap of the trip to Instagram with the caption:  'Well this will do rather bl***y nicely for the next few days. Lovely birthday surprise staycation from the even lovelier boyfriend.'

The Daily Mail have contacted Fifi's representatives for comment. 

Jon is the grandson of French film actress Marika Rivera and the great-grandson of Russian-born painter Marie Vorobieff known for her work with Cubism and pointillism. 

As well as modelling he has also appeared in independent movies X/Y, Kilimanjaro and Ass Backwards. 

Fifi's ex Andrew described  himself as an ‘artist and busker’ and runs an organisation called Dirtybeach, which creates sand sculptures on beaches to make sometimes light-hearted political and environmental points.

He once appeared on Dragons’ Den, dressed in a red kilt, with the intention of asking for £100,000 of funding to build litter-removing robots.

The producers edited out his idea, screening only his bid for £22,000 for a pop-up beach bar — which the Dragons turned down.

He told the investors he had been homeless in 2007 and had a ‘plethora’ of jobs. He even worked as a lap-dancer at Stringfellows. ‘I started out as an engineer,’ he said. ‘I was Father Christmas once.’

In 2014, the same year he proposed to Fifi, he launched a bid for a political career, making enquiries with the Electoral Commission about registering his own political party.

He published a manifesto for his Beach Party, whose policies included legalising drugs, and providing free food, travel and education 'at any age, regardless of sex, age, race, religion or species'.

'Your GP should have the power to prescribe you any drug you need, including cannabis and mushrooms for free,' he asserted just seven weeks after Fifi's younger sister Peaches died of a heroin overdose at 25.

It comes as the Geldof family prepare to mark the 12th anniversary of Peaches' tragic death as she .

Paula and Bob had three children together, daughters Fifi, Pixie and Peaches, before divorcing in 1996. He later married  in 2015, with the actress helping him raise his children following Paula's death.

As part of one of Britain's most famous families, they once

Yet when tragedy struck the clan in the Noughties, the trajectories of the famous brood veered in a very different direction.

Following her death, the Boomtown Rats star also adopted Paula's daughter Tiger Lily, whom she .

Bob became Tiger's legal guardian and officially adopted her in 2007, determined to raise her far from the showbusiness spotlight.

Bob has credited his second wife Jeanne with helping him to raise his daughters and previously said his children 'wouldn't have survived' without her.

The musician even proposed to Jeanne days after Peaches' death in a moment he said 'brought air into the room' when Fifi and Pixie were 'in agony'.

After Bob became Tiger Lily's legal guardian, it was also Jeanne's influence which helped support the then four-year-old through the difficult period.

Gerry Agar previously told the Daily Mail: ‘Tiger was totally raised and totally loved by Bob’s wife Jeanne, so she has such stability.

'They have been very strict with her and Tiger is incredibly unlike Peaches. She wants to please them.'
