Britney Spears has given her pregnant teenage sister Jamie Lynn advice on motherhood. Spears - mom to Sean Preston, two, and Jayden James, one - gave her sister pregnancy tips during an intimate baby shower at her parents' home in Kentwood, Louisiana on Saturday.

Jamie Lynn tells OK! magazine, "To be able to be in the privacy of our own home and just be sisters again was wonderful. She told me, 'There are going to be some long nights, but it is completely worth it."

The 17-year-old actress is due in June.
