Carly Rae Jepsen relished the opportunity to direct Tom Hanks on set

She said: "Tom was learning the lyrics, and there was one line he couldn't get. I timidly raised my hand and said, 'I know the words.'

And for one brief, beautiful moment I found myself directing Tom Hanks."

Carly previously revealed she wanted the 'Forrest Gump' star to be in her video so it wouldn't become too "sickly sweet".

She said: "Look, I'm a cheesy, nerdy Broadway girl at heart. It's a very flirtatious, adorable song but ... we felt like if we had a sickly sweet video it would just overkill ... My favourite bit (video) is where we sent 'running guy emoji', 'tree emoji' and 'running guy emoji' to Tom Hanks. Run, Forest, Run!"

The singer regularly gets compared to a young Carly Simon and considers it "a big compliment."

She added to PEOPLE magazine: "I've spoken with her a few times over the phone, and we might have a little surprise cooked up for later this year."
