Former singer Gary Glitter has admitted an 11-year-old girl slept at his house, but denies having sex, it is reported.
Glitter has adamantly denied any abuse
Glitter, 61, is being held in Vietnam under suspicion of committing lewd acts with children, which he has denied. He has not been charged.
News agency AFP quoted police who said Glitter had admitted the girl spent the night with him but denied all abuse.
Glitter said the girl had slept in his bed as she was afraid of ghosts, his lawyer told another news agency, AP.
Glitter - whose real name is Paul Francis Gadd - had his detention extended by four months last week, while claims he had sex with under-age girls, one aged 12, are investigated.
The girls are said to have had sex with the 1970s British rock star at his home in the resort of Vung Tau, where he has lived for the last six months.
But Glitter's lawyer Le Thanh Kinh said the singer had admitted to police that the girl and her aunt had come to his house, AP said.
After questions from police, Glitter "answered that when this girl [and her aunt] came to his house, he put them in the guest room. But in the middle of night, they said they were very afraid of ghosts and they cannot sleep. So they came to his room and slept there", Mr Kinh told AP.
Another time, Glitter told the pair they could not sleep in the same bed as him, but "the girls explained to him that in Vietnamese families, the father, the mother and the children sleep in one bed", the lawyer added.
The rock star also admitted he had swum with a number of girls in his pool, but again denied abusing them.
The lawyer added: "He said he thinks they are like his grandchildren."
Provincial police chief Lam Minh Chien told AFP: "He admitted to police last week that he had allowed a girl aged 11 to enter his house to spend the night with him but that he did not abuse her. The minor girl is from Vung Tau city.
"We have as yet no proof of this statement. He has so far rejected all accusations of sexually abusing children in Vietnam."
Under Vietnamese law, Glitter can be held for up to 12 months before charges are laid.
If convicted, Glitter could be jailed for up to 12 years.
He was stopped at Ho Chi Minh City airport on 19 November by an official who recognised him from media coverage.
There are conflicting reports as to whether the second girl linked to the alleged acts had turned 18 - the legal age of consent in Vietnam.
Glitter was found guilty in the UK in 1999 of possessing child pornography and served two months in jail.
