David Haye enjoyed a night out with his girlfriend Sian Osborne at the annual Lambertz Monday Night party in Cologne, Germany on Monday evening.

The boxer, 43, and his partner, 32, looked in good spirits as they posed for snaps alongside German actress Rebecca Kunikowski and gymnast Magdalena Brzeska. 

The outing came hours after the news that David’s ex Una Healy has reportedly split from her boyfriend Aidan Coleman, just a few months after she went public with their romance. 

David, who has been in a relationship with the model since 2020, raised eyebrows in 2023 when it was reported he was in a ‘throuple’ with both Sian and Una, claims roundly denied by Healy. 

The rumours were fuelled by the group posting cosy snaps of the trio on holiday in Morocco, both on the beach and while out for an intimate dinner.

Una later insisted that she was never part of a ‘throuple’, revealing the only person she was dating was David – although he was simultaneously dating Sian.

The outing came hours after the news that David’s ex Una Healy has reportedly split from her boyfriend Aidan Coleman (pictuered in November 2024) 

David raised eyebrows in 2023 when it was reported he was in a three-way relationship with both Sian and Una, which Una denied, saying she only dated him

David and Sian were all smiles at the event where the boxer also posed for a playful snap with German actor and ex-bodybuilder Ralf Moeller.

The Lambertz Monday Night party is an annual event that combines entertainment, networking, and food. 

Stars including Patricia Arquette, Matt Dillon, and Faye Dunaway have all attended in the past.   

A source confirmed Una’s breakup to the Irish Mirror on Tuesday, saying she and Aidan have ‘split amicably’ after several months of dating.

It seems the retired Irish jockey has already moved on as he’s been spotted on the dating app Bumble, with his profile reading that he’s looking for ‘fun’ and ‘casual dates’.

Aidan has also recently packed his bags and moved back to England after spending six months in Ireland, where Una currently resides, amid reports of the breakup.

In a recent interview with TDN live, he candidly admitted: ‘I am not a great sleeper at the best of times but I am very worried about the fact that I moved back to Ireland six months ago but just couldn’t settle here. 

‘My bags are packed and I am going back to the UK today—a place where I have spent half of my life—but I am worried that this move is not the answer, either. I hope it is. I really do, because I don’t want to feel like this for the rest of my life.’

Just a few months ago in November, Una revealed she was ‘very happy’ in her new relationship with Aidan, as she spoke about their romance for the first time. 

She arrived at the The Irish Post Awards at The Grosvenor House H๏τel in London where she opened up about her relationship with the retired jockey.

Una, who was joined by Aidan at the glitzy ceremony, told The Sun at the time: ‘He’s hiding on his crutches tonight, but he’s a great guy and I’m very happy.

‘He reached out to me and we met up and clicked. He’s such a kind and great person – I love him.’

However, after going their seperate ways it seems Aidan is already back on the market.

The Bumble profile, which is thought to be his, confirmed that he is residing in London now and includes pictures with horses.

There is also a snap of him on a boat from his travels and another of the retired sportsman unwinding as he smoked a cigar in a pub garden.

MailOnline contacted representatives for Una for comment.

Una was married to rugby player Ben Foden before rumours of him cheating put an end to things (pictured together in December 2017) 

Una was married to rugby star Ben Foden from 2012 until 2018 and has Aoife Belle, 11 and nine-year-old Tadhg with him.

They divorced after he was unfaithful to her and she started dating Limerick hurler David Breen that year but split with him by February 2020.

The following year she struck up a relationship with an unnamed Dublin-based police officer that came to an end in May 2022.

It was then reported that she was in a three-way relationship with David and model Sian – fuelling the claims by posting a cosy snap of the trio on holiday in Morocco.

Yet she went on to clarify that she was never actually part of a ‘throuple’, revealing the only person she was dating was David – although he was simultaneously dating Sian.

After calling an end to her time with David, she was said to be dating the voice of Love Island Australia – Stephen Mullen – in August but they split two months later.   

Last year, David’s ‘throuple’ pal Mica Jova hit out at Una for ‘trying to put a bad light’ on David and Sian.

In an exclusive interview with MailOnline, Mica, 28, slammed Una for speaking out against them.

She said: ‘David is one of the most gorgeous souls out there and Sian is a sweetheart. They are such good people so I really don’t understand why Una Healy is trying to put a bad light on those two.’

Mica added: ‘They were treating everyone right while I was with them, and they were so gentle, so they don’t deserve this.

‘They were two of the most gorgeous souls I have ever met and they are very cool people. I don’t regret anything in my life.

‘I had such a good time and I feel very grateful to have met them and to have them in my life.’

And David is clearly besotted with Sian, as he took to Instagram in February thanking his girlfriend for ’embracing his true essence’ on Valentine’s Day.

Sharing snaps of them on the beach, he wrote: ‘In the dance of life, you are the partner who has embraced my true essence, unconditionally.’ 

David added: ‘Amidst my rough edges, you guide me through a path of Love, wellness and creativity.

‘Our journey together is a wondrous adventure, and I yearn for its continuation indefinitely. Here’s to a Valentine’s Day filled with even more love and warmth.’
