News of the unlikely spat comes after Amanda Holden’s eight-year-old daughter Hollie suggested the couple had secretly split-up.

Tonight a source said: “Poor Lauren adores Simon but is naturally very suspicious of all the female attention he gets.

“Because he’s so charismatic, women flock to him – and it riles Lauren.

“Understandably, the fact she and Simon still aren’t married, despite having a son together, makes her a bit more insecure.

“Simon obviously gets on well with Mel and all his female co-stars, but that’s all there’s ever been to it; absolutely no hint of romance.

“They were both pretty livid – and mortified – when Lauren accused them of a ridiculous affair which never, ever happened.

“Things have been resolved now, and everyone is on good speaking terms – but, for a while, it was obviously extremely awkward.”

Former Spice Girl Mel, 44, quit the talent show last year – but her decision to go is not thought to be related to the 2018 incident.

Chatting to her 1.4million followers, she said: “I thought I’ll take [the album] round and have a cup of tea and see what he thinks, I don’t know why I did that – it was one of the most nerve-wracking things I have ever done in my whole of my life.

“I was sat in his lounge; I had some lovely homemade biscuits from Geoff the chef. I don’t think they have a chef in lockdown.
