Anthony Joshua was seen wearing what many believed to be a wedding ring at UFC London on Saturday (March 19) - but a simple explanation has now been offered for the accessory.
The two-time former unified heavyweight boxing champion was in attendance at The O2 alongside Frazer Clarke, Derek Chisora, Eddie Hearn and UFC chief Dana White - and their snap together has hijacked by eagled-eyed admirers.
With one fan writing: "Wait, is that a ring. No, please don’t break my heart." Many others followed suit before learning that he wears a £300 Oura Ring.
The ring is a high-tech fitness tracker rather than a symbol of marriage, and is said to help athletes record their heart rate, monitor skin temperature and even track sleep patterns.
Joshua has chosen to keep his personal life quiet despite being in the spotlight for a decade but does share a son with ex-girlfriend Nicole Osbourne.
The 32-year-old doesn't often speak about his dating life, but did say in 2020 that he doesn't really bother.
The Sun quote a source as saying: "AJ is so focused on his boxing this year that he is married to the game."

The upload came with the caption: "We Live & Breathe The Fight Game."
AJ has won 24 of his 26 professional bouts since claiming super-heavyweight gold at the London 2012 Olympics, losing to Andy Ruiz Jr. in 2019 and Oleksandr Usyk in 2021.
Joshua is said to be actively looking for a fight with a planned Usyk rematch now uncertain due to Russia's invasion of Ukraine.
When asked during an Instagram live whether the fight is going ahead, Hearn recently said: "Is AJ vs Usyk happening now? I actually think it will.
"I actually think that fight will happen next and it will happen in June."
With Joshua telling his social media followers last week: "Announcement soon come."
