Actress Mia Farrow has hinted the late Frank Sinatra may be the father of her 25-year-old son Ronan.

It was thought her ex-husband Woody Allen was Ronan's dad.

But when asked in a Vanity Fair interview whether rumours Ronan was actually Sinatra's son Farrow replied "possibly".

The BBC's entertainment correspondent Lizo Mzimba reports.
