She’s looking trim just 3 weeks after giving birth

She only gave birth 3 weeks ago to daughter Olive, but Isla Fisher already seems to have lost her baby fat.

Wearing fitted jeans and a kaftan top, the fiancée of Borat star Sacha Baron Cohen, 36, was snapped looking svelte while out shopping in LA yesterday.

In the last months of her pregnancy, the petite actress ballooned to such a size that she couldn’t fit inside her motor.

‘I used to drive a Mini Cooper,’ she said at the time. ‘I loved my little car but unfortunately my belly no longer fits under the steering wheel.’

Isla, 31, seems to have achieved her transformation without changing her diet.

She vowed to avoid any faddish eating regimes after having her daughter and is thought to have lost the baby blubber naturally through breastfeeding.
