Britney Spears' baby boy Sean Preston is already making waves in the culinary world - a new fruit smoothie has been named in his honour.

The pop beauty and her husband Kevin Federline welcomed their child into the world on Wednesday (14SEP05), and just a day later, a new beverage arrived on the menu of Spears' dad JAMIE's Venice, California, eatery JJ Chill.

JJ Chill co-owner, JOSEPH NEJMAN, says, "We're introducing a new smoothie in honour of Britney's boy. We're calling it the Preston Smoothie and it consists of only fat-free frozen yogurt, strawberries and mangoes."
