Lily didn’t tell dad Phil Collins about her song

British- American actor Lily Collins (right) wanted to surprise her father Phil Collins (below right), with her singing stint in her new film, Rules Don’t Apply.

“I didn’t tell him about the song until it was out in the trailer. I didn’t share what it sounded like. I didn’t give him any hints or anything. So I think that was kind of a surprise, which was fun,” said Collins.

She found the idea of singing the movie’s title song live on camera terrifying. “Marla is a songwriter — not a singer — so I got to use the excuse of, well, if my voice cracks as Lily, or I’m nervous, Marla would have been.”
