Britney Spears thrilled lunchtime diners at her favourite Malibu, California restaurant Moonshadows on New Year's Eve (31DEC05) when she turned up with baby Sean Preston.

The new mum has kept her son well away from the public in recent months but felt it was time to introduce the tot to one of her favourite haunts.

According to a fellow diner, Britney and her baby enjoyed a light lunch together overlooking the Pacific Ocean and the pop superstar seemed "very happy."
