I'm too young at 50. I'm not grown up yet. There's part of everybody like that.

I'll tell you how it happened. The phone rang. Paul, my agent, goes, 'Would you like to play Meryl Streep's?' I said, 'Yeeees! I'll do it, whatever it is.' He said, 'It's Mamma Mia!.' I said, 'Oh no, which character? The fat friend?

You can't help but feel a little bit like a mother to the younger cast members.

It wasn't being an alcoholic - it was going wild. It happened when I got famous. It was like having my teens in my early thirties: blotting out your life, not having to think about anything.

I don't like being out of the crowd. It's lonely within a group.

I'm more selective now I've got a family. I don't want to work all the time. My daughter's 12; I don't want to miss out on her life. Soon she'll be a teenager; she won't want me around.

I felt my mother about the place. I don't think she haunts me, but I wouldn't put it past her.
