Christina Aguilera gets Dirrty on the dance floor...with a mystery blonde

The singer famed for her hit single 'Dirrty'  danced seductively with a female companion in the exclusive nightclub as her husband Jordan Bratman looked on.

Dressed in a blue mini dress with a leather jacket the blonde singer and her companion put on a sexy show by dancing close to each other similar to the performance Christina put on in her 2002 video for her number one song Dirrty.

26-year-old Christina even grabbed her friend's head and rubbed her face into her breast as their racy dancing continued.

It was a night for Christina's husband to take the back seat as his wife took the limelight.

But it was not just her sultry moves that left him alone that night.

If he was the jealous type, he did a good job of hiding it at a party in Sin City .

Jordan Bratman was also left out in the cold as the pop star received a rather warm embrace from British jewellery designer Stephen Webster in the VIP section of LAX nightclub.

The pop star appeared in a series of Hitchcock inspired ads for Webster's company just months ago, and Christina has previously described him as a close friend she has known for many years.

She eventually returned her attention to her music producer husband, and the pair mingled with other guests at the club, which is part owned by Christina.

The couple, who welcomed their first child Max in January, were clearly making the most of a night off parenting duties.

But the couple are already planning to expand their family.

Asked recently if she wanted more children, Christina replied: "Absolutely . I can't tell you when, as I'm not planning things like that. Maybe around the next tour."

Christina's Back to Basics world tour was interrupted in August due to an unspecified illness.

Her pregnancy was later announced by socialite Paris Hilton to a nightclub crowd, before Aguilera herself confirmed the news.
