Singer Nicole Scherzinger says she doesn't know if she can act.

The singer is set to make her acting debut in the latest "Men In Black" film, which also has Will Smith, Gemma Arterton and Josh Brolin in lead roles, reports femalefirst.co.uk.

"I am excited. I grew up on the stage so film is still kind of new for me so I am learning a lot. I don't know how good I am at it," she said.

"When you are on stage, you are speaking to someone but when it's film you are sometimes not acting with an actor," she added.
