Ruth Langsford's legal team are pulling together a "forensic" timeline of Eamonn's new relationship ahead of divorce talks.
It follows reports that Eamonn, 64, and Katie Alexander, 43, were first in touch 12 years ago - when they reportedly exchanged flirty messages online. Sources close to the separated couple say lawyers acting for Loose Women favourite Ruth, 64, are compiling information on dates and times surrounding her ex's blossoming relationship.
And that they are prepared to speak to dating counsellor Katie's ex husband if needed. An insider said: "Ruth’s legal team are compiling a forensically detailed account of Eamonn’s relationship with Katie and when it started. Ruth's team are doing their due diligence ahead of the divorce proceedings. They are prepared to speak to people in Ruth and Eamonn's wider circle."
It was claimed last week that Eamonn and Katie had exchanged flirty messages online 12 years ago. The dialogue also involved Katie's husband George - who joked: "Think she's flirting with you."
Since that was reported, Eamonn and mum-of-three Katie have contacted their exes to reassure them their relationship only began once their previous ones had come to a definite end. The source added: "Katie and Eamonn have been scrambling around to tell their respective exes that they were not romantically involved way back then."
Following 14 years of marriage, TV couple Ruth Langsford and Eamonn Holmes - who have son Jack, 22, announced their shock split in May. The couple released a joint statement saying: "Ruth Langsford and Eamonn Holmes have confirmed their marriage is over and they are in the process of divorcing."
Ruth is said to have hired £400-an-hour lawyer Catherine Costley, who previously worked under the country's top divorce lawyer, Baroness Fiona Shackleton, who represented the King in his split from Diana, as well as Sir Paul McCartney.
Eamonn and Katie made their first public appearance as a couple this week, at the Irish Post Awards. Ruth recently made a joke at soon to be ex-husband Eamonn Holmes, while talking about hoarding. Speaking on Loose Women, she said: "I'm throwing out a lot of stuff out at the minute!" prompting laughter from the audience.
Eamonn and Katie are thought to have been dating for six months, already holidaying in Belfast and on a Mediterranean cruise.
Katie hails from Yorkshire and has a 22-year-old son called Ben with her ex, coach driver Michael Devine. The mum-of-three was previously married to bar owner George Alexander, with a son and a daughter together too. The couple separated in 2022, several years after she first made online contact with the GB News presenter.
George and Katie parted amicably, with Eamonn not linked to their split and he told how his ex stayed in contact with new pal Eamonn after her marriage ended. "I was surprised by it," he said. "Katie would go and visit him. It was a regular pattern."
While George's marriage break up had nothing to do with the TV presenter, some reports have suggested Ruth discovered in the year running up to their split Eamonn had been showering Katie with gifts. This included reportedly joining her at a safari park with her children and giving them Beyonce tickets.
Ruth and Eamonn's representatives were approached for comment. Ruth's declined to comment.
