David Haye packs on the PDA with model girlfriend Sian Osborne during a ... trends now

David Haye and girlfriend Sian Osborne packed on the PDA as they enjoyed a romantic stroll in London's Soho on Wednesday.

The boxer, 41, couldn't keep his hands off the stunning model, 31, as they walked together arm-in-arm before stopping for a smooch. 

Sian commanded attention in a black and white striped faux fur coat for the outing, which she teamed with a pair of chunky motorcycle boots. 

Meanwhile David donned an oversized aviator jacket with dark skinny jeans and Nike high-top trainers.

The pair chatted intently as they made their way along the busy street before stopping to grabb both a coffee and a kiss. 

Last month Una Healy reportedly split from her new Love Island star boyfriend after claiming she was tricked into a throuple with David and Sian.  

The Saturdays singer, 42, is thought to have begun dating Irish comedian Stephen Mullan in August. 

Una was backstage supporting him at the Paddy Power comedy festival with the comedian reportedly telling his friends that they were together. 

The pop star proudly shared a snap of Stephen on stage as she watched and described his set as 'silly yet cut-throat comedy'.

But the duo are now thought to have split after just two months of dating, with Una back on the market once again. 

A source told The Sun: 'Una and Stephen had lots in common with their Irish background but realised it was the end of the road for their romance.' 

However, a representative for Una has denied the two were ever officially in a relationship and had merely enjoyed a few dates in each other's company. 

They said: 'They were never in a relationship, it was just a few dates.'
