Kate Moss was interviewed by detectives in London Tuesday about her alleged cocaine use.
The Metropolitan Police doesn't identify suspects being interviewed by name, but said a 32-year-old woman "has voluntarily attended a London police office in relation to a Met investigation into allegations of possible drug abuse, as reported in newspaper reports."
Moss' modeling agency, Storm, didn't immediately return a request for comment.
Stuart Higgins, a spokesman for Moss, has said that she had agreed to be interviewed by police.
Police said she had not been arrested.
The 32-year-old supermodel lost valuable contracts with H&M, Burberry and Chanel after the Daily Mirror tabloid in September published pictures of her allegedly using cocaine in a west London music studio where her then-boyfriend, rock musician Pete Doherty, was recording with his group Babyshambles.
Moss has been out of Britain since the drug allegations broke, visiting a rehab clinic in Arizona and working on international assignments.
