Former EastEnders stars Kara Tointon and Joe Swash had a series of heated arguments at a pantomime production, reports say.

The real-life couple, who played Dawn Swann and Mickey Miller in the BBC One soap, clashed after Tointon found something on Swash's mobile phone, according to The Sun.

A source said: "Halfway through the first act Kara was walking around backstage looking for Joe with his BlackBerry in her hand.

"She'd obviously found something on it and she confronted him. They ended up in a quick-change dressing room next to the stage having an argument.

"You couldn't hear what was being said, but arms were being waved and he was trying to get his BlackBerry off her."

The source added that things remained "icy" and Swash later told his girlfriend that the relationship was over.

However, Tointon seemed to confirm otherwise, saying: "We were having a little mess around, but everything is fine."
