As cited in the Daily Mail, Neeson's Blacklight co-star Yael Stone was fans' prime suspect.

That was until the Australian actress sarcastically shut down rumours, declaring in "more factually accurate news" she does appear in the movie "for one scene."

"As I mentioned to @amyschumer yes, it's totally me. I guess he couldn't hold the secret any longer," she penned. "In even crazier/more factually accurate news I am actually in this movie… for one scene. I did it for my dad."

Attention soon turned to Australian music icon Tina Arena, 54, who has been with artist Vincent Mancini since 2000. There was even speculation about Neeson's love interest being Kylie Minogue's sister Dannii, 50,

Neeson's late wife, Natasha Richardson, died at 45 from an epidural hematoma (bleeding in the brain) in 2009. The actress hit her head during a skiing lesson in Quebec, Canada.

Speaking about his grief, Neeson told Anderson Cooper in 2014: “She was on life support. I went in to her and I told her I loved her.

"I said, 'Sweetie, you’re not coming back from this, you’ve banged your head,'

“She and I had made a pact, if any of us got into a vegetative state that we’d pull the plug. That was my immediate thought, 'Okay, these tubes have to go. She’s gone.'"
