According to the Daily Mail, Pete cheated on Kate last Thursday with a South African model that he met at a bar called the Crystal Club. An insider said, "Pete and Kate had a serious argument and he decided to go on a bender. Kate was calling around to see if anyone knew where he was, but everyone rallied around him to keep her in the dark."

An onlooker described Pete's interaction with the model, Lindy: "He ended up talking to this girl in a revealing tight dress. They went on the street for a while then came back, where they had an intense chat for ages. There was lots of flirting and laughing." Pete and Lindy were seen kissing and went back to Pete's friend's house later that night.

Two days later, on Saturday, Kate fled to Paris with her daughter Lila Grace. She has reportedly set up several photo ops in France so that posed pictures of her enjoying herself can make their way back to Pete.

A source said, "Kate is a mess. She's trying to keep it together for Lila's sake, but she's been sobbing and wailing uncontrollably all weekend…Kate has had enough, she has some serious decisions to make about the future of her relationship with Pete. She is supposed to be marrying him, so she's furious at the accusations of his cheating. It really is make or break."
