Pregnant Dannii Minogue spoke of her wardrobe crisis after being presented with a gong by her sister at a glittering ceremony.
The X Factor judge (38), who is expecting her first child in the summer with model boyfriend Kris Smith, received the TV Star honour at last night's Elle Style Awards.
Minogue was on a whistle-stop visit to London before returning to her home country to judge Australia's Got Talent.
After receiving the award from her sister Kylie, she revealed her struggle at fitting into a pair of jeans.
"I can't get any of them on and buy jeans with stretchy bits at the front," she said. "The rest, I don't even know how it works."
Supermodel Naomi Campbell was presented with the the Outstanding Contribution award at the event.
The 39-year-old was honoured for her 25-year career and her work as global patron of The White Ribbon Alliance (WRA), which promotes safe pregnancy.
Claudia Schiffer was named Model of the Year. She said on the red carpet that her mother had advised her happiness was the key to a healthy pregnancy -- so she was avoiding scary movies.
Bafta winners Carey Mulligan and Colin Firth were named Actress and Actor of the Year, while Twilight star Kristen Stewart was presented with the Elle Style Woman of the Year award by editor-in-chief Lorraine Candy.
Actor-turned-musician Jared Leto presented the Editor's Choice award to TV presenter, model and DJ Alexa Chung.
Ms Candy said: "Alexa Chung is incredibly popular because she always looks so glamorous and I think she's a real leader for style."
Mary-Kate and Ashley Olsen were named Elle's Style Icons of 2010 and Florence and the Machine won the music prize, given by Corinne Bailey Rae.
