Reece Hawkins' ex London Goheen sparks engagement rumours as she shows off her giant diamond ring after debuting romance with restaurateur Tosh Berman

Reece Hawkins' ex London Goheen has sparked engagement rumours, months after going Instagram official with top LA restaurateur Tosh Berman.

Tosh took to Instagram Stories over the weekend with a photo of London cuddling up to her son Stone at Disneyland, when fans quickly zoomed in on a huge diamond sparkler on her ring finger.

Curiously, neither Tosh nor London has made mention of an engagement, nor shared any further images of the ring on their Instagram feeds.

The sighting comes as a surprise to fans, given that London only went public with Tosh in November.

At the time, both London and Tosh shared identical photos on their respective Instagram feeds showing them cuddling up at a seaside restaurant in the Maldives.

'Hi from us,' London captioned the cosy image.

A day later, the couple both shared another photo of themselves attending a friend's wedding. 

However, it was a telling post one week later that hinted at an impending engagement.

At the time, London shared a photo of the pair cuddled up under the sunshine, adding the caption: 'Forever'.  

Tosh is a mega-wealthy hospitality entrepreneur best known as a co-founder of The Madera Group, the company behind popular Mexican-inspired dining concepts Toca Madera and Tocaya Organica. 

He has built a reputation for creating high-impact restaurants that blend food, design and atmosphere, helping shape Los Angeles’ modern dining scene and expanding his concepts beyond California.

London's happily ever after comes four years after her shock split from ex-fiancé Reece, the father of her child. 

Reece is also father to two children with his ex-fiancée Tammy Hembrow - son Wolf and daughter Saskia.
