As her boyfriend Tom Sturridge walked the red carpet alongside A-list pals Robert Pattinson and Kristen Stewart in Cannes, Sienna stayed at home and enjoyed the sun in London.

The smiling actress looked glowing as she stepped out with her bump to attend a yoga class in London's super-stylish Primrose Hill.

Donning a pretty printed frock for her outing,Sienna shaded her face with a summer hat, accessorising her summer look with a leather belt, suede boots and a handful of gold chains.

Earlier this month, Sienna told us she's been enjoying regular yoga classes during her pregnancy, but isn't a fan of the gym.

'I have been trying to do some pregnancy yoga, as I'm definitely not a gym person,' she revealed.
