The Cajun cutie held up one of the Boston rockers' CDs as she made her way out of Starbucks' parking lot yesterday afternoon with her son Sean in the backseat. Hey, it's never too early to start acquainting your kids with the classics!

Meanwhile, Entertainment Weekly has learned that Brit's fifth album will debut as early as next week, and the single - an up-tempo club cut produced by Timbaland protege Nate 'Danjahandz' Hills entitled "Gimme More" - is "a smash," reports an insider. Another source raves that "people are going to love [the new single]." So exciting!
