Carey Mulligan is reportedly pregnant with her first child.

The 'Great Gatsby' star and husband Marcus Mumford of Mumford & Sons are said to be expecting a baby.

A source told Us Weekly magazine: ''They weren't planning on announcing, but she hasn't stopped working.

''Everybody around her is being very supportive. The show ['Skylight'] ends soon and they're going back to England after.''

Whilst things are making progress in her personal life, Carey recently admitted she is looking forward to things moving forward in her career and is ''excited'' that she's starting to look older.

She said: ''I spent a lot of my early 20s playing teenagers because of my baby face. My agent has started saying, 'You've been offered this part, she's 19, you're too old', and I'm like, 'I'm too old? Brilliant! I've never been too old'. All the great parts come now, I think, so I'm excited.''

Carey hopes her ''older'' looks means she can play ''darker'' characters in the future.

She added: ''I like dark characters, and it's fun to do things that are difficult, because I'm very happy and have had a very lovely, charmed life, lovely parents, lovely family and lovely education.

''It's very easy to play things that you know - it's when you have to play things that you don't really understand that it gets fun.''
