Sienna Miller wore a straw hat to protect her face from the sun, and donned a multi-coloured strappy dress to cover her baby bump.

She threw a knitted waistcoat on top and added flat khaki suede ankle boots to complete her look.

The 30-year-old accessorised with a brown belt and bag plus a waist-length necklace.

It is thought that Sienna Miller's baby is due in July, so the actress has a few weeks left yet.

She spent the day with her sister Savannah plus her stepmum Kelly Hoppen earlier this week, for Kelly's daughter Natasha Corrett's healthy lifestyle guide launch.

Sienna Miller and Tom Sturridge enjoyed a babymoon in Italy earlier this month, and she told InStyle ahead of the trip: "I'm going on holiday soon, which will be lovely; it's a pre-baby, last hurrah trip.

"I'm in the mood for lying on a beach, reading a lot of books and a bit of culture. I like being able to walk into an old town and find good local food."

Sounds bliss.
