Olivia Colman isn't "any good at" singing and dancing.

The 50-year-old actress had to show off her musical talents as a nun in 'Paddington in Peru' and while she enjoyed the scenes very much, she admitted the performing element didn't come naturally to her.

She told Best magazine: "I did really enjoy it. It's not something I would say I am any good at, but I had a lot of wonderfully talented people to help me.

"Also wearing a really long habit that covers your feet is a very handy way to hide all the steps you get wrong.

"But I did do all the dancing.

"It was dancing, singing, acting and playing the guitar all at the same time I had the most trouble with.

"I only had to do one song but it was very hard for me."

And Olivia admitted she had to spend a lot of time preparing for the musical numbers.

Asked about her preparation, she said: "Most of it was the singing and dancing. That took a lot.

"The rest was really about the costume and make-up.

"When you dress as a nun, it's hard not to find yourself acting like one."

The award-winning actress - who has two sons, aged 19 and 17, and a nine-year-old daughter with husband Ed Sinclair - was thrilled to be cast in the movie because her kids are such fans.

She said: "They love it. My youngest was really excited when I told her - almost as excited as I was!

"But as a family, we've watched 'Paddington' again and again since our kids were very small.

"So it was huge to be asked to be a part of this and more than a little surreal. I couldn't believe it was real at first."
