Sienna Miller is pretty in blush-pink Burberry at the Tony Awards

Sienna Miller walked the Tony Awards red carpet in style last night.

The Girl actress donned blush-pink Burberry as she joined fiancé Tom Sturridge in New York.

Mum to 11-month-old Marlowe, Sienna looked pretty in a strapless, ankle-length gown that flaunted her enviable cleavage.

The actress looked radiant as she flashed the flash in the ruched number by the Brit fashion house.

The 31-year-old fashionista kept things simple accessories wise, styling the dress with a pair of classic nude pointed heels.

Her fiancé Tom Sturridge – who was nominated for Best Performance by a Leading Actor in a Play for the show Orphans – also opted for Burberry on the red carpet.

The Brit actor, 27, looked stylish in a classic black suit with an on-trend bowler hat.

Sienna showcased a pretty beauty look too - opting for mauve-coloured lipstick and floral hair jewellery.

This isn’t the first time Tom and Sienna have worn Burberry recently – they’ve worn Christopher Bailey’s label religiously over the past month.

Perhaps those rumours about them being the face of the brand’s AW13 campaign have some truth to them after all?
