Bruce had previously claimed he was indifferent to having more children with Emma, as the only thing that mattered was being with her.

He said: 'I'd like to have a thousand more children, or zero more children. It doesn't matter. Emma makes me feel great.'

The jolly 58-year-old looked completely happy as he stepped out on the family outing.

The Expendables favourite held just a cup of coffee as he enjoyed the December weather in a brown leather jacket, bodywarmer, scarf, combat trousers and trainers.
But for once all eyes were on his radiant wife Emma who seemed to be relishing showing off her adorable daughter Mabel as they did the shopping.

The glamorous English model looked in fine form in a green jacket, a pink top which showed off her bump, jeans and trainers.

Bruce previously explained how fatherhood had taught him to keep his mouth closed, saying 'Sometimes I have to resist the urge to speak
'I learned it from dealing with my kids. That's my number one rule. It applies in life. But it's more about being a father.
'I'd rather hear what they have to say. You learn more by listening.'
A spokesperson for Bruce Willis declined to comment.
