The 'Rocky IV' actor dated the 'Pull Up to the Bumper' hitmaker in the 1980s and though he admitted their life in the bedroom was eventful, he insisted it wasn't always a "good thing".

He told The Sun newspaper: "That happened on occasions, with or without Grace.

"Sometimes she would bring a girlfriend home and then I'd have to get up for work the next day and that kind of thing.

"I'd say at the most it was four or five girls, perhaps.

"It's great in theory but when you have to get up and fight Sylvester Stallone in the morning it's not such a good thing."

Dolph, 60, met Grace, 70, when he was hired as her bodyguard but once he found fame after playing notorious villain Ivan Drago in 'Rocky IV', their relationship quickly deteriorated.

He said: "I literally walked in the theatre [for the movie premiere] as her boyfriend with people trying to shoo me out of the way to take pictures of her and, 90 minutes later, when I walked out, people were trying to take pictures of me, instead.

"It was one of those things that happens once in a while in Hollywood, somebody totally unknown becomes famous overnight.

"Other women showed up, she got jealous and she couldn't handle it. People wanted me to go to openings.

"It was a lot of strain and, within six months, the relationship was over."

During their relationship, Dolph admits drugs were rife in New York but he never joined the 'Slave To the Rhythm' hitmaker's "circle" in indulging in "heavy" substances.

He said: "Back then everybody in her circle was doing heavy drugs -- cocaine, crack and smoking weed.

"I didn't know anything about drugs, I was just training at the time.

"This was before drugs were a menace to society, it was just rich people who were having fun at Studio 54.

"They weren't breaking into cars stealing s**t and killing people so nobody cared.

"You could do drugs openly in a restaurant in New York in the Eighties and nobody would say anything, not even the waiters.

"It was fine at the time."
