The Strictly Come Dancing star thinks the actress has the perfect body.
'Halle Berry has an amazing figure,' Kelly, 30, tells Now.
'She's really toned, not too skinny and she's got gorgeous skin. She always looks beautiful, whether it's in a bikini or on the red carpet.'
Kelly - who is dating rugby player Danny Cipriani, 22 - also admires Dita Von Teese, 37.
'She's so beautiful,' she says. 'She looks effortlessly chic whether she's in a Dior suit or a 50s dress.'
