David Haye is in a three-way relationship with The Saturdays singer Una Healy and model Sian Osborne.
The “throuple” grew close last year, then spent time together in London over Christmas before a New Year’s getaway to Marrakech.
They have told family and friends of their arrangement.
Ex-heavyweight boxing champion David, 42, has dated Sian, 30, since 2020 when she worked for his Black Mask Company.
Una, 41, joined them in Ibiza in October to celebrate his birthday.
This week she shared a photo on Instagram of David holding hands with both her and Sian.
She captioned it: “I’ve started 2023 in a comfortable place, feeling genuinely happy and at peace. Here’s to this year being ours x.”
Fans were confused, with one asking: “Are ye all together?”
Radio 1 DJ Melvin Odoom wrote: “I wish I had two girlfriends.”
David posted an Instagram snap of the three in a pool, with his arms around the bikini-clad women.
He wrote: “If a picture says a thousand words, then this one says exactly what it needs to.
“I’ve started Jan first with the correct energy, surrounding myself with understanding beautiful human beings, who do not judge, but instead accept me for my authentic self.”
He added that during the luxury getaway in Morocco he had enjoyed a “90 minute four-handed massage” — alongside a winking emoji.
David has a son from a marriage that ended in 2016.
Una was wed to rugby player Ben Foden, 37. They have a daughter aged ten, and son, seven, but split in 2018 after it was revealed he cheated on her.
Irish-born Una later had romances with a Limerick hurler and a Dublin-based policeman.
She told The Sun last year: “There are nights when I can stretch out without anyone sharing the bed.
“But there are nights where I’m like, ‘I would quite like an arm around me’.”
Una is now back in Ireland with her children while David has flown to Costa Rica with Sian. Their representatives did not comment.
Haye was the world’s best cruiserweight in the mid-2000s before moving up to heavyweight and shocking the sport by defeating seven-foot Russian giant Nikolai Valuev.
