Elizabeth Hurley's ex-boyfriend, producer STEPHEN BING, has donated $4 million (GBP2.2 million) to a group fighting proposals to strip California lawmakers of power.

Bing, who is the father of Hurley's son DAMIEN, is opposed to Proposition 77, and as such is battling against California Governor Arnold Schwarzenegger, who is expected to spare no expense to back the controversial measure.

Bing's donation is the largest ever given to University Of California professor DANIEL LOWENSTEIN's special-election campaign to stop the legislation going through.
