Keira Knightley Was 'Completely Terrified' to Sing in 'Begin Again'

Keira Knightley makes her way through Heathrow Airport after arriving back home on Monday (April 28) in London, England.

The 29-year-old actress took a quick trip to New York City to attend the premiere of her new movie Begin Again held during the Tribeca Film Festival.

“I was completely terrified,” Keira recently said of singing in the movie. “I didn’t anticipate being as frightened as I was. I said yes to doing it and I was (like), ‘Oh, it’s gonna be fine, it’s gonna be fine,’ and then suddenly I found myself in a studio with real people who did it for a living and I was like, ‘I don’t know what I’m doing. I’m pretending.’”
