Kristen Bell has hinted she is expecting a baby boy.

The 'House of Lies' star is expecting her first child with fiance Dax Shepard and as she discussed her car-fanatic partner's excitement about ''all the off-roading he'll have in this tiny partner,'' she was asked if the traditionally-masculine pursuit meant she was having a son.

She replied: ''Maybe?''

She then added to TV talk show host Ellen Degeneres: ''Do you have to be a boy to off-road? Absolutely not! I think he's going to force [the baby], even if it's a sloth, to off-road.''

The 32-year-old actress also admitted she is open to taking all the pain relief she is offered when she goes into labour.

She said: ''I've got nothing to prove [by having a natural birth].

''I feel like, when I arrive at the hospital, I want a glass of whiskey, I want the epidural in my back and I want to get hit in the face with a baseball bat and wake me up when it's over because I've seen the videos - and it looks terrifying.''

And Kristen also spoke of her pride in her looks at the moment, admitting she feels more attractive than ever.

She said: ''I look in the mirror and I think it's the reverse body dysmorphia because I can understand what my shape is, but I see Brooke Shields. And it doesn't make a lick of sense, but it's something that the baby's giving me hormonally makes me feel really giggly and happy.''
