A glowing Billie Piper proudly showed off her baby bump as she strolled through the streets of Paris.

The 25-year-old actress and husband Laurence Fox, 29, are enjoying a city break in the French capital ahead of the arrival of their first child.

The former Doctor Who star is expecting their baby in October.

Waiting for baby: Billie Piper rubs her expectant belly as she walks through the streets of Paris with husband Laurence Fox

So in love: The couple enjoy the sights of Montmartre

Dressed in a tight-fitting, thigh-skimming black dress, Billie clearly feels confident of her ever-changing body.

Billie rubbed her belly as she and Laurence strolled arm-in-arm through the Paris district of Montmartre.

The busy couple have taken time out of filming their TV series - Billie's The Secret Diary Of A Call Girl and Laurence's detective drama Lewis - to enjoy a few days together.

A source said: 'Laurence and Billie are having a lovely time and are taking in all the sights.'

Billie has been forced to enlist a body double for her ITV call girl drama, which calls for her character Belle De Jour to strip down to her underwear.

Billie said: 'I needed two body doubles in the end.

'As I got more and more pregnant I began to gain weight so it looked silly having a really skinny body double.'

Billie and Laurence wed on New Year's Eve in West Sussex after a whirlwind one-year romance.

The actress was previously married to DJ Chris Evans, who married golfer Natasha Shishmanian.

Billie remains on good terms with her ex, who recently announced his wife is also expecting.
