Dolph Lundgren is engaged.

The 62-year-old action star proposed to personal trainer Emma Krokdal - who is in her twenties - a week ago in Stockholm.

Dolph shared a picture of them on Instagram, with Emma showing off her engagement ring, and wrote: ''Something very special happened here in Sweden. D[heart emoji]E.''

His close pal Sylvester Stallone was one of the first to congratulate him, writing: ''Congratulations my good friend. You're the best. Sly.''

Dolph - who was previously married to Anette Qviberg from 1994 to 2011 - reportedly started romancing Emma last year and they went public at the Cana Dorada Film & Music Festival in the Dominican Republic in January.

Dolph previously revealed how he used to have group sex with Grace Jones and ''four or five'' other women - but complained it left him too tired for work.

The 'Creed II' 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 said: ''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 met Grace 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.''
