Olivia Newton-John's daughter Chloe savagely mocked after 'trainwreck' interview

Olivia Newton-John's daughter Chloe Lattanzi has been savaged over her new look by viewers of an Australian TV show after her appearance on it.

The clip was posted on Twitter along with comments saying she looked like a porn star and got a boob job for exposure as she lacked the skill and talent of her mother.

Lattanzi, whose father is actor Matt Lattanzi and maternal great-grandfather is Nobel prize-winning physicist Max Born, wore a low-cut lace black top while promoting a new designer equestrian range.

The 31-year-old has undergone various operations that have resulted in her ample cleavage, plump lips and current facial features.

Lattanzi told The Morning Show hosts she was "comfortable in her own skin", but faced a bit of embarrassment over the term "doo-dah" - believing it was slang for marijuana.

The awkward moment was seized upon by tabloids who labelled the interview a "trainwreck".

Lattanzi, an aspiring singer, has battled a series of health problems in the past and has sought treatment for eating disorders and substance addiction.
