Al Pacino has reportedly split from his Argentinian girlfriend Lucila Sola.
The 75-year-old star and the 36-year-old actress have gone their separate ways after four years together following a series of rows.
A source told The Sun newspaper: "They are so close but it wasn't meant to be.
"They're both dedicated to their craft so sustaining a relationship was always going to be tough."
The Oscar-winning actor has never been married, but hinted in March that he was willing to tie the knot with Lucila, despite there being a 39-year age gap between the pair.
He said: "I never say never. It's possible."
Meanwhile, the 'Godfather' star - who has a grown-up daughter, Julie Marie, with an ex-partner and 14-year-old twins Anton and Olivia with former girlfriend Beverly D'Angelo - recently revealed how he struggled to cope with fame during the peak years of his career, in the 1970s and 1980s.
The Hollywood legend reflected: "I was having difficulty with all the attention.
"I was a drinker, for sure, my career was exploding in the Seventies and, I'm sorry, but I don't remember much of the Seventies. Now when I come to think about it, I don't remember much of the Eighties either.
"I have a little bit more of a grasp of the Eighties. I no longer drink or take drugs or any of that. I haven't done for the past 30 years."
