Britney Spears has reportedly registered online for thousands dollars worth of baby gifts at the upscale children's store Petit Tresor in LA. A source says, "Oh, it's not fake, she's having a baby shower soon and has told friends that they can order gifts from the site. It's not like she's expecting her friends to buy everything for the baby. She's already spent like $30,000 at the store." The items Spears has picked out are rumored to primarily be pink and frilly, suggesting that the Federlines are expecting a sister for baby Sean.
