Just a week after confirming her pregnancy Jennifer Garner showed off her blooming baby bump on a trip out to lunch in Los Angeles yesterday.

Dressed in flat gold ballet pumps, loose denim jeans and a floaty smock top the actress showed she has already mastered a comfy pregnancy style.

And she has had plenty of time to do so, with unconfirmed reports that the 36-year-old and husband Ben Affleck could be welcoming their second baby as soon as October.

Jennifer Garner shows off her growing bump

After weeks of speculation over her burgeoning belly, the Juno actress only publicly acknowledged she was pregnant at a launch in LA last week.

She said: 'We're so excited, obviously... It's all good, it's great.'

Jennifer and Affleck married in the Caribbean in June 2005, welcomed their first child, a daughter Violet the following December.

Relaxed: Mother-to-be Jennifer head home

Yesterday Jennifer joined her former Alias co-star Victor Garber for lunch at Orso Restaurant.

Garber, who is a close friend of the couple, revealed the pregnancy to the American Us Magazine in an interview in July.

'Yes, she is'  he replied when asked if the couple were expecting.

But Garber's indiscretion seems to have done nothing to dampen the friendship. After their lunch he and onscreen daughter Jennifer disappeared for 90 minutes, leading to speculation from onlookers that he had accompanied her to the nearby Cedars-Sinai Hospital.
