I look at his hand on her leg and it sends a shiver up my body. It landed so confidently on her. So solid and firm. He leaves it there and rubs it up and down. She shuffles her chair along so it’s closer to his, and he puts his arm around her as if she is cold, even though it’s very hot in this weird room. Lauren is childlike, I decide. Not the confident, bubbly person she puts on display on her Instagram feed. From what I have seen, there is always someone, or something, supporting her. Whether it be physical contact from Gav, emotional propping from her mother or reassurance from Jenny, someone is always egging Lauren on. She’s not the person you would expect to meet, the one who takes her clothes off a lot, who talks about happiness and confidence like they come naturally to her. To me she seems quite lost. Or maybe I am just projecting.

The hand on the leg is causing me distress. I can’t imagine easy breezy affection like that. It’s so rare that Michael makes any physical connection with me at all. The concept of my husband touching me should not feel so alien.

‘OK, so music,’ I say, snapping myself back to reality. ‘I have the DJ booked for later on. And I spoke to Bastille’s manager, they are absolutely up for doing the first dance as well as the later set. All they’ve asked for are snacks and a few bottles of champagne, which is no problem. Would you like me to invite the band to the wedding breakfast?’

‘For sure,’ Gavin says, squeezing Lauren towards him. He is so tactile with his wife-to-be. The rumours of infidelity that surround him are hard to believe when he seems incapable of taking his hands off her.

Lauren smiles, shyly. Gavin runs his hand up her leg and it takes a hard push of professionalism from me to keep my focus on the job. I once heard that he shagged Felicity Smithe, a model, in the toilet of a restaurant during a lunch sitting while Lauren was waiting at the table. Apparently one of the waiters saw them walk in together and leave a few minutes later. It’s one of those whispered celebrity gossip stories that everyone seems to know, but never made it into the papers. In fact there are a number of those rumours floating around about Gavin. It’s not impossible to imagine that they might be true. Physically he is little short of perfect. And then of course there is the money and power. Women must throw themselves at him all the time. But yet, he chooses to marry Lauren Pearce. I have so many questions that I plan never to ask.
