Helen Skelton reportedly hired a private investigator after becoming suspicious about her husband Richie Myler's behaviour in the months leading up to their split.
The 38-year-old Countryfile presenter shared on her social media last month that the rugby ace, 31, left her after nine years together.
Just last week, it was reported he had already started a new relationship with a new woman - 31-year-old Stephanie Thirkill.
