Jamie Lynn Spears - Baby shower details ???

17-year-old pregnant actress Jamie Lynn Spears celebrated the upcoming birth of her first child with a baby shower on May 2nd. OK! magazine spoke exclusively to the Zoey 101 star, who seemed to be happy to be reunited with her big sister, Britney Spears. “It was wonderful to be able to spend time with her and just be girls again,” she says. “To be able to be in the privacy of our own home and just be sisters again was wonderful.”

How did the reunited sisters spend their time? “We painted our nails and did stupid stuff,” she says.

Britney, who is the mother of two children with ex-hubby Kevin Federline, gave her little sister some words of wisdom. “She told me, ‘There are going to be some long nights, but it is completely worth it,’” Jamie Lynn reports.

Will Britney be returning to Louisiana when Jamie Lynn has her baby? “Nothing is set in stone, but that would be wonderful. I’d love to have her here for that, but you can’t plan that far ahead,” Jamie Lynn tells OK! magazine.
