Una Healy’s rumoured ‘throuple’ relationship with David Haye and his girlfriend Sian Osborne may have welcomed a ‘new woman’ into the relationship, it has been reported.
Thanks to some cryptic Instagram posts from boxer David and Una over recent weeks, rumours have been rife the mum-of-two and the sports star are in a 'throuple' with model Sian.
David and his girlfriend Sian reportedly used celebrity dating app Raya to find a partner to join their relationship last year - with the pair eventually 'hitting it off' with Una.
The former world heavyweight boxing champion, 42, has reportedly told his friends and family how he is now in a 'throuple' with the two women – after both he and Una shared cryptic captions on Instagram earlier this month.
But now, David and his girlfriend have been spending time with swimwear designer Antonia Christopher in Costa Rica.
The 26-year-old designer posted a slew of stealthy pictures on her Instagram with high-end meals for three people, three sun loungers beside an infinity pool and three pairs of feet kicking back on a speedboat.
Meanwhile, earlier this week, David and Sian were seen enjoying time with a mystery woman as David posted a video of his feet appering to be touching the toes of two women while on a boat during the sunny getaway.
The clip showed David relaxing on a boat alongside two women in a montage video which he posted on his Instagram story and wrote "#nofilter" on – but the identity of the women was not made clear.
Meanwhile, Antonia posted a video of David and a group of men pushing a boat out into the sea, which she tagged David and another male holidaymaker in and wrote: "Bromance" on top.
However, it is not known if the swimwear designer's relationship with David and Sian is platonic or romantic.
The Mirror has contacted a representative of Una Healy and David Haye for a comment.
Rumours Una was in a 'throuple' with David and Sian began after the singer had posted a snap of herself posing in a pool last month in Morocco before boxer David joined the former singer with Sian for a snap of all three of them in the pool.
"Happy new year and may 2023 be everything you hoped for," David captioned his post.
"If a picture says a thousand words, then this one says exactly what it needs to."
He added that he started the year 'surrounding myself with understanding beautiful human beings, who do not judge' but accept him.
