Peaches Geldof puts wild child past behind her as she attends The Muppets premiere

Practising family-friendly fun: Pregnant Peaches Geldof puts wild child past behind her as she attends The Muppets premiere

She used to be famed for her less than angelic behaviour.

But domestic bliss appears to have changed Peaches Geldof, who these days favours family films over nightclubs.

The pregnant 22-year-old attended the premiere of The Muppets in London tonight, perhaps practising for the years of animated entertainment she has in front of her.

Peaches, whose baby boy is due on
April 24, cradled her bump as she posed for pictures at the screening,
held at the Mayfair Hotel.

Miss Geldof wore a demure black and white dress with opaque tights and brown and black heels.

The rock offspring is still looking incredibly slender in her face and arms despite being six months into her pregnancy.

The former party girl described herself in a recent interview as 'domesticated' and 'boring.'

'I’ve been staying in with my fianc
every night of the week, watching films like Babe,' she told Hello!
magazine. 'The most exciting it got recently was a night out to see
Arthur Christmas.’

It's a
good thing her taste in entertainment has changed, as with a baby on
the way, Peaches has at least a decade of child-friendly films in her
future.

The former Ultimo spokesperson and her rocker fianc revealed their happy news earlier this month, after enjoying it in secret for as long as they could.

Peaches told how she announced to her family over Christmas that she was expecting, and that father Bob Geldof was overjoyed at having a grandson.
