David Haye has caused a stir on social media after appearing to reveal his new throuple partner in a picture posted on his Instagram account - after his love life reportedly inspired a new reality show.The 42 year old athlete, who retired from boxing in 2018, shared a picture of him and his girlfriend, model Sian Osbourne, posing with another woman on the beach in Costa Rica. David is grinning at the camera as he rocks some black swimming shorts with his arm around both his model girlfriend and another woman, who has been identified as Serbian travel influencer Mica Jova.The cosy snap has set tongues wagging as fans wonder if David and Sian have found another woman to join their throuple, months after their very public split from former The Saturdays singer Una Healy.
