Sophia Loren defying her age at the Charitable Foundation Federation gala auction in Moscow

Sophia Loren is defying her age by refusing to tone down her outfits or cover up her curves.

Sophia Loren, 77, showed off her impressive figure in Russia last night as she stepped out in a floorlength gown with a daring low cut.

The iconic actress was joined by her eldest son Carlo Ponti Jr. as she wowed in the black gown with intricate detailing on the bust and sleeves.

Most women her age would be trying to cover up their skin and opt for dowdy items.

But Sophia Loren clearly isn’t most women as she happily posed with her cleavage on full show as she cuddled up to Carlo.

Sophia Loren looked tanned and happy as she held her son’s hand, who was dressed in a dapper suit with white shirt and bow tie.

And she wasn’t the only one who upped their glamour stakes as they showed up to the Charitable Foundation Federation gala auction in Moscow.

Carmen Electra was also on hand as she walked on to the red carpet in a pretty yellow frock emblazoned in diamante.

And she looked more comfortable back to doing what she does best following her unsuccessful bid to impress Britain’s Got Talent viewers with her monotone appearance.

Carmen Electra ensured she looked her best for the event with her hair half up and wavy.

Actress Andie MacDowell also attended, as she also defied her age of 53 with her black lace frock with a plunging neckline.

Former American Idol judge Paula Abdul was also a star guest and went for a floorlength white dress with a black panel around her waist.

Paula, who was recently dropped as The X Factor USA judge, accessorized with a small black clutch bag with her hair worn down.

But it was a fashion miss for singer Craig David, who turned up to the glamorous bash in some odd head wear.

The star looked dapper in a beige suit with a white shirt and thin black tie.

But he failed as he completed the look with a tight black hat that looked like a swimming cap which covered up his hair.

Brigitte Nielsen was also on hand as she wore a strapless pink dress to the event.
