Kiwi chocolate-maker Whittaker's is considering whether to keep using Nigella Lawson in TV commercials after allegations the celebrity cook used cocaine.
This week, two of Lawson's former personal assistants claimed as part of their defence in a British fraud trial that the celebrity TV cook was a regular drug user.
Lawson's ex-husband, millionaire art dealer Charles Saatchi, accused her of being "off her head" on drugs while they were married, but has since backed away from the claims.
Whittaker's yesterday said it was disappointed about the revelations and had discussed the issue at a "senior level".
Whittaker's last year signed Lawson to promote its new 5 Roll refined chocolate in a TV ad campaign. The company, which prides itself on its family-friendly and trustworthy image, said Lawson's contract with it had ended in October.
