Hollywood stars Brad Pitt and Jennifer Aniston will be fighting a bitter legal battle over their $190 million fortune.

Hollywood's former golden couple had reportedly failed to sign a prenuptial agreement when they married in 2000, said imdb.com.

Pitt and Aniston - who announced the end of their four-year marriage earlier this month - now face a showdown over their combined assets, which include a $15.2 million mansion, a $5.7 million yacht, a ranch and the film company Plan B.

British newspaper The People was told by a source that lawyers are already giving each star the kind of advice that is not in the other person's best interest.

"A major row is on the cards. It's only a matter of time. The word in the divorce community is nobody did a prenuptial. That's surprising because of the huge sum of money involved," the source was quoted as saying.
