As per Dame Helen Mirren, they didn't just date  - they were a serious item.

Former couple Liam Neeson and Helen Mirren reunited on the couch as they joined chat show host Graham Norton and actor Jamie Dornan.

The couple met on the set of fantasy flick "Excalibur". Neeson (65) recalled the moment the actress first walked towards him, dressed in her iconic Morgana Le Fey costume. The "Taken" star revealed he was hit by Cupid’s arrow instantly - although, awkwardly, so was his “oldest friend” and co-star, Ciaran Hinds.

Neeson and Mirren (72) would go on to be an item from 1980 - 1985.

The County Antrim native previously said of his time spent on the "Excalibur" set with Mirren,

"She was so sexy. I thought, gosh, that’s Helen Mirren! She was as beautiful up close as on stage. Just so human. I was in love with this extraordinary human being. Can you imagine riding horses in shiny suits of armor, having sword fights, and you’re falling in love with Helen Mirren? It doesn’t get any better than that.”

While their courtship didn't work out - the two evidently still have the utmost respect and admiration for each other. As seen in this clip from The Graham Norton Show below.

Neeson moved to Hollywood in 1987, where he landed his big breaks in films like "Schindler's List". He would go on to marry "The Parent Trap" star Natasha Richardson in 1994. The couple had two children together, before Richardson was tragically killed in a skiing accident in 2009.

Soon after she split from Neeson, Mirren met and began dating the American film director Taylor Hackford. She has been married to the Oscar winner since 1997.
