Legendary screen siren Lauren Bacall has lashed out at Tom Cruise, branding the actor "a maniac."

The leading lady slams Tom for leaving ex-wife Nicole Kidman heartbroken and swanning off with Penelope Cruz in a bizarre rant to a U.S publication.

“Tom had taken off for Penelope Cruz or some g***mn thing — one of his more ridiculous moves," she tells Elle.

“Tom Cruise is a maniac. I can’t understand the way he conducts his life.”

Luckily for Tom, Nicole has been more understanding, recently telling Elle that the actor taught her a lot during their 11 year marriage.
