LATEST: Fears that Olivia Newton-John's partner PATRICK KIM McDERMOTT has purposely disappeared have grown after it emerged he was financially ruined and his son had allegedly turned against him.

McDermott, 56, who had been dating the GREASE star for nine years, was $30,000 (GBP16,658) in debt when he declared himself bankrupt and his present finances had reportedly not improved.

In April (05) McDermott battled in court with his former wife, actress YVETTE NIPAR, and was ordered to pay $800 (GBP445) per month for the upkeep of their 15-year-old son together.

But McDermott recently fell behind on the payments and court authorities listed him as a 'deadbeat dad' - a father who refuses to pay maintenance - and had engaged the services of an enforcement agency.

McDermott has not been seen since 30 June (05).
