Amy Macdonald has said she will contact the police and admitted being in tears over a false claim that she had tweeted an anti-Catholic message.

The development came after the Scots singer criticised England footballer Stan Collymore in a row over his linking of Rangers and Chelsea to right wing groups such as Combat 18.

Macdonald spoke out after the Talksport pundit said he we was vindicated as reports from Ireland claimed one Chelsea fan hunted for pushing a black man off the Paris underground was a former Royal Ulster Constabulary officer and had been a Rangers fan.

In the aftermath, a doctored photograph surfaced on Twitter which falsely represented that the Scots singer had tweeted a message containing a sectarian sentiment.

The fake tweet, made to look as if Macdonald had sent, it said: "Oh, no Pope of Rome. No chapels to sadden my eyes. No nuns and no priests. F... yer Rosary beads. Every day is the 12th of July."

The unknown perpetrator subsequently deleted the fake account as Macdonald raised concern about the content.

She tweeted: "Unfortunately there seems to be loads who think it was (genuine) and I've ended my weekend in tears.

"Trouble is so many others happy to spread the bile. It's disgusting.

"I will have to talk to the police about this tweet. So many people write utter crap and then so many others base their opinions on it. I try my best but I'm only human."

Some users who retweeted the photograph and drew it to Collymore's attention later apologised to the singer.

BT Sport withdrew Collymore's invitation to appear on their Friday night coverage of the Raith Rovers v Rangers match after a row exploded over his call for a boycott of the club over some fans' sectarian singing.

The row began after he commented on Twitter about the racist incident in Paris, where a black man was pushed off a train by a group of what appeared to be Chelsea supporters travelling to the Parc des Princes stadium for a Champions League match against Paris St Germain.

Collymore, who is also a Talksport analyst, tweeted: "As I said a couple of weeks ago, Rangers and Chelsea, aka 'The Blues Brothers', made for each other. Quelle surprise.#NF #BNP #C18."

Macdonald entered the fray after Collymore remarked: "So the ex RUC officer who #CFC want info on and pushed the guy off the train is indeed a Rangers & Chelsea fan. Vindication complete."

Macdonald hit back: "What utter crap. I support Rangers. I'm not racist or sectarian. I have no interest in Chelsea and I'm NOT an anomaly."

A Police Scotland spokeswoman said they were unable to confirm if an official complaint had been made by Macdonald.
