On hearing the rumours that the boxer David Haye is in a ‘throuple’ – a three-person romantic relationship – with Una Healy from the Saturdays and a model named Sian Osborne, I felt a rare flicker of carnal pique. Apparently Victoria Beckham is off her feed (a prawn and two capers) with worry that her baby boy Brooklyn might be in a throuple with his wife Nicola Peltz and singer Selena Gomez, while Rita Ora is still denying that she and her now-husband Taika Waititi were in one with the attractive actress Tessa Thompson a couple of years back.
