Coleen Nolan has called off her Never Too Late tour which included a date at Scarborough Spa.
The TV personality and singer has cancelled all her work commitments following her on-screen row with Kim Woodburn on ITV’s Loose Women.
Ofcom received more than 7,000 complaints about the episode, with viewers accusing Nolan and other panellists of bullying Woodburn.
Nolan, the youngest of the Nolan sisters, will not appear on Loose Women until further notice and her solo tour Never Too Late is being postponed.
A statement on her Twitter account said she is “devastated” to let people down.
But said she is “not strong enough to withstand ... constant and unfounded online abuse”.
Nolan broke down in tears when she talked about her rift with Woodburn, who presented How Clean Is Your House.
The feud started when both women appeared in a series of Celebrity Big Brother and Woodburn called Nolan a bully.
Woodburn appeared on Loose Women last week when attempts to reconcile the duo were shattered when Woodburn walked off the set branding NOlan a bully and ‘lying trash’.
Nolan said the row was “ugly, upsetting and unpleasant”, adding that she she wished she could turn back time and undo it.
But, she said: “Anyone that knows me knows I’m not a bully. That would be the most hurtful thing people could call me.”
She said she has experienced “constant online bullying, trolling, and misrepresentation of her words, actions and re-actions”.
“Coleen has spent 50 years in show-business and 18 years as one of the most loved members of the Loose Women panel, and has never been subjected to such a horrifying torrent of online abuse or such a heart-breaking attack on her reputation,” said a statement.
“She sends her love to everyone who has supported her and knows who she really is and plans to return when she feels stronger.”
