Now David, 42, has had his say – and suggested former The Saturdays singer Una will be easy to replace.

Sharing a snap of him and Sian posing with a trio of women, he wrote: “We experienced an unexpected opening in our team, but the invigorating atmosphere at the @sxmfestival ensures that we’ll soon have a full roster.”

Una David and Sian, 32, grew close last year, then spent time together in London over Christmas before a New Year’s getaway to Marrakech.

But the Irish singer later told the pair she wants to focus on her family.

The mum-of-two has since then broken her silence on her relationship status.  

Speaking to the Irish Mirror: “I am single and raising my two children, just like many other single parents – both men and women – doing a great job.

“I am a single parent. I don’t like the term single mother as it has negative connotations.

“You can’t do it all by yourself. There is no shame in asking for help, be that from childcare, family or friends.

“I am often asked how I juggle it all as a single parent but men aren’t asked that.

“In fact, I can never remember a time when I heard a man being asked how he juggles it all.”

Back in January boxing legend David sparked rumours that he was dating  Una after they appeared on social media together on holiday in Marrakech, Morocco.

Una later fuelled throuple rumours with the boxer as he held hands with her and model Sian in a cosy holiday snap.

Then The Sun exclusively revealed that the trio were in a throuple and had told their friends and family.

But weeks later Una called it off.

Tensions started to rise when Una was only able to join them for a short visit on holiday in February.

It has put increasing tension on their relationship, with the women struggling for the heavyweight champ’s attention.
