LOST star Naveen Andrews was branded a 'prostitute' by his own father for having a scandalous affair with his teacher during his teenage years.

The British actor, now 36, fell in love with GERALDONE FEAKINS in 1985 when she started giving him out of hours tuition before his exams, and he got more than just good grades when the married maths mistress bore his child - JAISAL, now 13.

A former pupil tells London's newspaper the Evening Standard, "As an actor he's famous for being that 'Sikh bloke' in The English Patient and the rather naughty boy in The Buddha Of Suburbia.

"But he was famous at school for going out with a maths teacher."

Andrews recalls, "My father would call me a prostitute."
