The couple had gone for a romantic meal and the former Page 3 model, 40, continued drinking whilst the Essex lad, 25, went to bed earlier this week, according to a pal of his.
But she was overheard declaring her love for her former boyfriend, 29, in the early hours of the morning.
The source close to Alex told the Sun he had been telling pals about the awkward encounter and he is done with the mother of five.
They said: “Alex and Katie went out for dinner and drinks. When they got home, she continued to drink whilst Alex went to bed.
“Alex woke up in the early hours of the morning and caught Katie FaceTiming Kris Boyson and overheard her telling Kris she still loves him.”
Katie and the wealth businessman began dating following her split with Kris last month.
The pair were first pictured together leaving The Blue Boar pub in Abridge, Essex on August 22.
Soon after they were seen on holiday together in Mallorca.
Yesterday the Sun revealed Alex has a secret one year old son called Leo.
It was also revealed friends of Katie are worried he has become too controlling as he takes over her dwindling finances.
An insider said: “Alex has several investments in businesses and says she should put the tiny amount she has left into those companies as an investment.
“He’s grown up in a wealthy family, but was never given anything on a plate. His father was very strict and wanted him to learn the value of money from a very early age.
“Alex is very strict about money and thinks Katie needs to take charge of her debts.
“He wants her to make lists of her creditors and how much she owes down to the last penny.”
