Christina Aguilera gets cosy

If Christina Aguilera's husband is the jealous type, he did a good job of hiding it at a party in Sin City last night.

Jordan Bratman was left out in the cold as the pop star received a rather warm embrace from British jewelery 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.
