Dame Helen Mirren has one of the sexiest celebrity stomachs in the world

The 63-year-old actress – who recently wowed onlookers with her trim physique when she donned a bikini while on holiday in the Italian Riviera – came third in the poll, which was carried out by stomach-flattening supplement AntiBloat.

AntiBloat spokesperson Jalal Janmohamed said: "The survey results reveal that a sexy stomach isn't governed by age, which is good news for all those wanting to tone up or maintain a flat tummy.”

‘Umbrella’ singer Rihanna topped the poll. The 20-year-old Barbados-born beauty is renowned for her revealing stage outfits and shocked fans with a variety of bondage-style costumes during her tour earlier this year.

British actress Keira Knightley came second in the survey.

The ‘Pirates of the Caribbean’ star is famous for wearing midriff-flashing costumes, and has bared her taut abs in movies including ‘Bend It Like Beckham’ and ‘King Arthur’.

Keira’s ‘The Edge of Love’ co-star Sienna Miller – who showed off her enviable toned figure in a skimpy bikini while on holiday recently - secured fourth place on the list.
