Kristen Bell doesn't want any more children.

The 34-year-old actress already has daughters Lincoln, 23 months, and Delta, two months, with her husband Dax Shepard and is adamant they won't be adding to their brood unless she accidentally falls pregnant with her third child in the future.

When asked on the 'Ellen DeGeneres Show' if she's planning to have any more kids with her beau, she said: ''No. No, no. We don't want to be outnumbered.''

She quipped: ''Until, I suppose, I accidentally get pregnant and my third child watches this clip and realises that he was an accident. Sorry, honey. No, but we're gonna cap it at two.''

The blonde beauty explained that Dax, 40, whom she married in 2013 after being engaged for three years, already feels outnumbered being the only man in the house.

She said: ''He likes to say he never thought he'd be surrounded by so many women and not having this much sex.''

Meanwhile, the 'Veronica Mars' star endured a painful 33 hours in labour with Delta in December, before eventually delivering her via a Caesarean Section.

But it was Dax who felt he had suffered the most because he had to experience the emotional journey as well.

He said recently: ''Kristen, God bless her was in labour for 33 hours. It was incredible.This was intense. And she got an epidural like hour 14, as you should, and I think dads need something. I deserve something because I was along for the ride. It's still a car crash and I'm in the passenger seat.

''I'm playing Katy Perry and I'm rubbing her back and I'm thinking, 'I need something for this! Help me!' ''
