She may have turned 50 this year, but Sharon Stone has just as much pulling power as ever before.

The Basic Instinct star raised eyebrows as she turned up with a mystery toyboy at designer pal Christian Audigier's Caribana Saturday party in a Toronto nightclub.

Despite being a mother-of-three, the actress showed she still plenty of energy to party until the early hours with her young beau and a host of twenty-somethings.

Dressed in a white, ruffled mini-dress and leopard-print heels, Sharon looked toned and tanned as she held hands with her baby-faced companion.

Sharon's mystery beau also opted for white to compliment his famous date.

The couple were inseparable throughout the night as they partied at Toronto's Tonic nightclub.

The fresh-faced man is just the latest mystery man to be linked to Sharon.

In May this year, Sharon was photographed cuddling a tanned older gentleman on board a yacht docked near Cannes.

The mother-of-three has been single since splitting from San Francisco Chronicle editor Phil Bronstein in 2004.

The film star is mother to adopted sons Roan Joseph, eight; Laird Vonne, three; and Quinn Kelly, two.

The actress caused a controversy at the Cannes Film Festival when she suggested the China's horrific earthquake was the result of bad karma over their government's treatment of the Tibetan people.

She said: 'I'm not happy about the way the Chinese are treating the Tibetans because I don't think anyone should be unkind to anyone else.

'And then this earthquake and all this stuff happened, and then I thought, is that karma? When you're not nice that the bad things happen to you?'

After her comments were received badly by the international community, Stone apologised: 'Due to my inappropriate words and acts during the interview, I feel deeply sorry and sad about hurting Chinese people.

'I am willing to take part in the relief work of China's earthquake, and wholly devote myself to helping affected Chinese people.'
