Jemma Kidd sparked engagement rumours on Friday after she was spotted wearing a huge diamond on her ring finger.

The make-up artist, 48, wowed onlookers in a dazzling black dress as she left Mayfair’s 5 Hertford Street arm-in-arm with her billionaire partner Arpad Busson, 59. 

But it wasn't the frock that attracted attention. Instead, it was a diamond encrusted ring, placed on her ring finger. 

Heading home for the night, she could be seen clutching a Saint Laurent handbag with her decorated finger.

She then placed a hand on her beau as she whispered into his ear. 

Engagement rings are a contentious subject for billionaire Arpad ‘Arki’ Busson, who previously accused Pulp Fiction star Uma Thurman of failing to return the £1.2 million sparkler he bought her after they called off their wedding plans. 

Friends of Arki’s, were intrigued by the huge gold ring, with multi-coloured encrusted diamonds, that she wore on her ring finger for the night out.

‘It was the talk of the club,’ one member told the Daily Mail's Eden Confidential.

They recently made their red carpet debut together as they attended the Fashion Trust Arabia Prize 2022 at The National Museum of Qatar in Doha.

Jemma wowed onlookers in a dazzling red sleeved gown for the event.

She and Arpad went Instagram official earlier this year, posting a holiday snap together in St Moritz, and have kept a fairly low profile until now.

French financier Arpad went for smart casual, pairing black tie with Nike Air trainers.

Former model Jemma split with her husband Arthur Wellesley, the Marquess of Douro, in 2020.

Luckily, she seems to have found love again with Arpad who appears to have a penchant for leggy blondes.

He was previously with Australian supermodel Elle Macpherson between 1996 and 2005. They share songs Flynn, 24, and Aurelius, 19.

Earlier this year, Jemma and Arpad looked cosy as they were seen together for the first time while holidaying in St Moritz.

Jemma sported a striking fur hat while Arki gripped a furry blanket to keep out the cold.

Aristocrat Jemma and Arki had been flirting at exclusive London members’ club 5 Hertford Street in May last year.

Things have moved on considerably since then, with the couple enjoying a horse-and-cart ride and dinner dates in the luxury resort.

Jemma’s 15-year marriage to Arthur Wellesley, the 9th Duke of Wellington’s elder son, ended amicably in 2020, while Arki was once Uma Thurman’s fiancé.

The pair have colourful family histories. Arki’s step-grandfather, Hungarian financier Arpad Plesch, had a prized collection of esoteric pornography.

Jemma’s great-grandfather, Sir Rowland Hodge, was convicted of hoarding 168lb (6oz) of bacon and ham during the First World War.
