Demi Moore goes dirty dancing in Las Vegas with Snoop Dogg (in front of Ashton)

Perhaps she had taken a few tips from her late friend, Dirty Dancing star Patrick Swayze.As it certainly seemed that Demi Moore knew her stuff as she performed some sexy dancing moves with husband Ashton Kutcher and rapper Snoop Dogg in Las Vegas this weekend.

The 47-year-old actress was initially happy to sit and watch the rapper perform as she perched on her 32-year-old husband's knee.

She showed off her slim legs in a slinky black mini dress with a revealing open back while Kutcher looked more casual in checked shirt and jeans. But not content to be out of the spotlight, Moore enthusiastically got up to join Snoop on stage where she performed some classic 'bump 'n' grind' moves alongside him.

The Ghost star then tried to persuade her husband of nearly five years to come up on stage to join her.

The celebrity couple were in Sin City to attend a Fantasy Football event and concert at Rain nightclub at the city's swanky Palms Hotel. And it seems they had a good night, with Kutcher taking to his Twitter page to reveal he was a little bit worse for wear the day after the event.

'I think I injured my brain last night and I can't seem to find my voice,' he wrote.It's not the first time Moore has been spotted in party mode recently. She was seen dancing in the street, beer bottle in hand last week, after she and Kutcher spent the day partying at a friend's house in Malibu.

Following her impromptu Vegas performance, Moore posted a more intellectual image of herself on her Twitter later on that evening, which featured she and Kutcher sporting matching dark rimmed glasses.

She captioned the image with the slogan: 'Boy do we look smart.'

Moore has just been filming financial thriller Margin Call alongside Kevin Spacey and Paul Bettany, while Kutcher has just been seen starring in action comedy Killers with Katherine Heigl.
