“It's a bit of a passion killer to have your mum in the house," The Sun quoted a source close to Ashley, as saying.
Joan, 50, started living at the couple's Surrey mansion two years ago after the soccer star was first accused of cheating on Cheryl with hairdresser Aimee Walton. She is said to be furious over Cole's infidelities and is fully behind her daughter's decision to split.
Meanwhile, Cheryl is angry at Cole's mum Susan, who has tried to act as peacemaker and put her son's side of the story. Cole bombarded Cheryl with calls and voicemails after she ditched him by text from the US.
When she did not reply, Susan rang to try to explain his feelings. However, Cheryl left the calls unanswered.
“The mothers have understandably become embroiled in the marriage break-up. Joan is comforting her daughter while Ashley's mum has tried to make the peace," a source said. “Obviously she loves him no matter what and believes the marriage could have been saved," the source added.
