Minnie Driver showed off her huge baby bump as she enjoyed a swim at a Malibu beach yesterday.

The 38-year-old actress/singer is seven months pregnant with her first child, but has declined to name the father.

A day after celebrating the impending birth with a baby shower at a friend's home in the beachside LA suburb, Minnie spent the day relaxing on the beach.

Dressed in a white tankini, it appears Minnie found the blistering California sunshine too hot for her huge baby bump and rolled up her top to create a makeshift bikini bra.

Despite living most of the year in California, it appeared Minnie has been sheltering from the sun given her pasty skin colour.

On Saturday, Minnie's best friend hosted the actress and 40 friends at a beachside baby shower.

The house was decorated in pink and white peonies and the food on offer included finger sandwiches and berry cake from Sweet Lady Jane.

Guests were invited to customise babygrows and write personal notes to Minnie in her baby book.

Last month, the Good Will Hunting star denied reports Californian musician Craig Zolezzi was the father of her unborn child.

She said: '"I want to shield the baby's dad as much as I can because it wasn't his choice to get roped into all this stuff.

'It'll come out in time. There'll be some other bump people will be interested in and I'll have this baby and get on with my life.'
