Jackie Chan mistook Michael Cera for a competition winner

Speaking to NME, Michael explained a photographer told him Jackie was in the building.

He added: "She asked if I knew Jackie Chan, which I don't, so she said 'come meet him'. That was that.

"When I met him though, he was like 'who is this person, what's going on?'. We took a picture but I think he thought I was a competition winner.

"He was like, 'OK let's do a picture real quick. Come on.' Not rudely. But I felt like I was invading his little personal time with his team before he goes on the radio.

"So I was like, 'What am I doing here?' But everyone was very sweet and I got to meet Jackie."

The 36-year-old actor is a big fan of the Beatles and though he thinks it would be "cool" to meet surviving band members Sir Paul McCartney and Sir Ringo Starr, he'd also find it "weird".

He said of the possibility: "It would be cool but also strange. I don't know what I'd say [if I did meet them]. It would be weird to say anything. They'd be so bored by whatever I had to say, because they've heard it eight billion times from every other person on the planet. It must be hard to be a Beatle."

Michael - who has two sons with wife Nadine - released his debut album 'True That' in 2014 but hasn't released further music since 2017's 'Best I Can' and admitted he simply doesn't have the time to work on any at the moment.

He said: "I haven't really been creating any music recently.

"I play music every day but I have little kids now, so I just don't have time or focus to do anything productive in that way. I hope to again though.

"Normally [everything I make] is for a specific project or has a specific intention but it's just my time management [right now]."
