'I'm worried Kate Moss' daughter will be exposed to drugs' claims grandfather

The grandfather of Kate Moss' only daughter has hit out at the supermodel's drug addict boyfriend, Pete Doherty, amid fears that the four-year-old will be exposed to drugs.

Speaking for the first time about his daughter-in-law's love life, Douglas Hack has said that he does not want Lila Grace anywhere near the Babyshambles singer.

'We're worried about Doherty and his drug situation,' he said. 'We don't want Lila around him or drugs.

'But Kate is headstrong. She's going to do whatever she wants and who can tell her otherwise.

'It's not like she's listen to us anyway, she just loves the whole rock thing.'

The 32-year-old model has been dating Doherty, who, until recently, was in rehab undergoing treatment for heroin and crack cocaine addiction, for 18 months.

Although Miss Moss remains close to her in-laws, her relationship with the 27-year-old singer is badly effecting her friendship with the father of her child, Jefferson Hack.

Indeed, Douglas, 68, revealed that his son 'can't stand' Doherty. 'Jefferson doesn't like Pete at all,' he told Closer magazine.

'They've been in the same room a couple of times, but really just by accident. He left as soon as he saw him, Jefferson can't stand him.'

He also claimed that Croydon-born Miss Moss was dissatisfied with her modelling career - despite the fact it has earned her £30 million this year alone.

According to her father-in-law, who lives with his wife Teresa, 60, in Ramsgate, Kent, the mother-of-one hopes to be a singer.

'She'd love to be a rock star herself,' he said. 'That's why she hangs out with that crowd the whole time. She doesn't really like modelling that much.'

While Miss Moss' aides and close friends, including her best friend Sadie Frost, have been quick to air their concerns about Doherty, the Hacks have previously refused to publicly discuss the troubled star.

Douglas' comments come 13 months after the supermodel was photographed snorting line after line of cocaine in a west London recording studio.

With her modelling career in turmoil - she had contracts with both Burberry and high street store H & M terminated - Miss Moss was forced to check into rehab in Arizona. She missed her daughter's third birthday as a result.

During her stint in therapy, she was advised to dump her rock star lover, and the pair spent four months apart.

But since reuniting earlier this year, Doherty has spent much of his time in court after repeatedly being caught driving while under the influence of drugs.

Last month, whilst staying at London's Priory clinic, Doherty was reportedly caught punching a nurse in the face and providing a teenager with cocaine.

Miss Moss is understood to have footed the £1,200 a day bill herself.
