Kristen Bell is already preparing for Christmas.

The 'Frozen' star - who has Lincoln, three, and 22-month-old Delta with her husband Dax Shepard - has revealed the family are well on their way to prepping for the winter festivities.

She said: ''Just before Halloween, I start thinking about Christmas. It just makes you feel so good. My family was always really into Christmas and my husband and I decorate like crazy.

''We start early. I just took the Christmas light boxes down. I haven't put them up yet, but a lot of my neighbours have. I have really radical neighbours - the electric bill on my street, I cannot even fathom.''

And the couple think it is more important for their children to focus on the gifts they are giving out rather than on what presents they get.

She told Entertainment Tonight: ''We focus more on, 'What do you want to get other people?'

''And wrapping other gifts and saying, 'This is a time to spoil everyone else.' We try to take them volunteering and we tell them they can ask Santa for three presents.''

Meanwhile, the 36-year-old actress previously revealed her house is like a ''circus'' because her kids are always ''screaming bloody murder''.

She said: ''It's a circus. It's a circus for sure. I love it. I love them. But, you know what? You know where we could do better? Why does everyone wake up screaming?

''Like, why don't they tell you that? Like, 'they're going to wake up screaming for, like, four years.' You wake up - the moment you wake up, you're in, like, a horror movie, because everyone in the house is screaming bloody murder!''
