(makeushot.com) - Laura McLaughlin is 3 months pregnant and claims she was a virgin before spending a weekend with Pete at the Berkeley Hotel in London's Knightsbridge in October.
The 20-year-old - who is the god-daughter of Manchester United boss Sir Alex Ferguson - says she conceived when a condom split.
'The baby is Peter's,' says Laura. 'There is no doubt about that.
'I told him I was pregnant the moment I found out shortly after Christmas. We are only in contact by phone.'
The child is due in June, but Laura says Pete's not interested.
'Our weekend together wasn't just about sex,' she tells The News Of The World. 'We cuddled up to watch the movie Dirty Dancing together.
'His apathy has been traumatic.'
But 28-year-old Pete's spokesman denies the claims: 'Pete says he doesn't know who this girl is.'
The Babyshambles frontman is currently linked to 19-year-old model Portia Freeman and already has a 4-year-old son with ex Lisa Moorish.
