MTV's fly-on-the-wall look at Ozzy and his family is proving quite a success...

A deal for two more series of the MTV hit show ‘THE OSBOURNES’ could be worth up to $20 million, according to reports.

In the US the show, which is a fly-on-the wall look at the life of Ozzy Osbourne and his family, has become one of the most popular in the history of the network, regularly attracting up to eight million viewers.

The Reuters news service reports that negotiations are underway for two more runs, and it could be the largest payout for a cable series.

However, a deal has not yet been signed with negotiations ongoing. The final amount paid could depend on its continuing success.

An MTV spokeswoman said. “Because there is no deal, any numbers or facts reported are unreliable,”

‘The Osbournes’ will receive its UK premiere on May 19.
