UNA Healy is believed to have jetted abroad with David Haye and his girlfriend Sian Osborne for a sun-kissed holiday.
The singer, 41, has reignited rumours of a throuple after flying out to Costa Rica - where David and Sian are also staying.
Una has not been snapped alongside the pair, however she has shared her own pictures from the picturesque destination in Central America.
The former Saturdays star, who was previously married to rugby star Ben Foden, shared a selfie on Instagram while posing in her luxury accommodation.
Wearing a bright orange bikini top and patterned flared trousers, Una ran her hand through her hair as she looked in the mirror.
The mum-of-two has also posed for a sultry close up selfie, gazing at the camera in a purple bikini top.
Una filmed a reel of her stay, too, captioning it: "Pura Vida."
David, meanwhile, has shared a picture of himself and two male friends. It was taken as they soaked up the sun on the beach.
The ex-heavyweight boxer, 42, captioned it: "Livin La Pura Vida here in Costa Rica.
"Nothing but good vibes and banta!! Ireland’s truly been representing out here… Until the next adventure."

His girlfriend Sian, meanwhile, posted a snap of herself in a sun hat. The 30-year-old model also captioned it: "Pura Vida."
David has been in a relationship with Sian since 2020.
Una was married to Ben between 2012 and 2018. The former England rugby union star remarried Jackie Belanoff Smith almost a year to the day after their split.
Last month, The Sun revealed that David is in a three-way relationship with Sian and Una.
The “throuple” grew close last year, then spent time together in London over Christmas before a New Year getaway to Marrakech.
The trio have told family and friends of their arrangement.
Their reps did not comment when approached by The Sun.
Last year, Una - who was single at the time - said: “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’.”
