RYAN & TATUM O' NEAL WAR

The new reality show Ryan and Tatum: The O'Neals is turning into an ugly family feud!

While friends thought the show would bring the once estranged Love Story star and his daughter closer, sources say the opposite has happened.

"Ryan and Tatum are at each other's throats every time they film, and they fight about everything," an insider divulged.

Ryan, 69, and Oscar winner Tatum, 47, had been estranged for 25 years

During that time, she battled heroin and cocaine addictions and Ryan demons of his own.

The reality show follows the drug-addled stars as they struggle to overcome their substance abuse and rebuild their stormy relationship.

But their behavior while filming at Terra restaurant in Malibu stunned eyewitnesses.

"Ryan and Tatum were eating when they suddenly started arguing - loudly.

"They shouted at each other for a good 10 minutes and then, with other diners staring at them, stormed off - leaving the camera crew to pick up the tab.

All the details are in the new ENQUIRER -- including their first attempt at a reunion considered "sick".
