Reality TV star Kerry Katona has been dropped as the face of supermarket chain Iceland following new allegations that she took drugs.
The News Of The World published photographs and video footage of the 28-year-old mother allegedly showing her snorting cocaine in her home in Wilmslow, Cheshire.
Iceland said last night that while the company had stood by her during earlier personal difficulties, it was now "impossible" for her to continue in its advertising campaign.
The former Atomic Kitten singer, who has endured a long and public battle with alcohol and drugs, as well as a roller-coaster romantic life, fronted the supermarket's advertising campaigns for four years.
In a statement, Iceland said: "For most of that time, she has been a successful part of our advertising campaigns, but has also been through some tough times in her personal life.
"We have always stood by her, as an example of a normal person and mum who has experienced some of the modern-day culture of fame, and how difficult it can be to deal with.
"However, following the most recent allegations, we feel it is impossible for Kerry to continue to work with us as one of the faces of Iceland advertising.
"In recognition of the relationship we have developed, we will continue to try and help Kerry to ensure she get the most appropriate support, should she require our assistance."
Katona, who had two children with Westlife singer Bryan McFadden and two more with Mark Croft, won the Best Celebrity Mother award in 2004 and 2005.
