Jamie Lynn Spears is expecting a boy – if a recent trip to an exclusive baby boutique is any indication.

According to insiders, the pregnant teen picked up several ‘light blue’ items from the Petit Tresor store in West Hollywood, during a whirlwind visit with elder sister Britney on February 25.

A source tells MSNBC’s The Scoop: “Britney originally said the items were for herself.”

However, the source says of the purchases – which included organic baby blankets, towels and pajamas: “None of the items could have been mistaken for being purchased for the two kids Britney already has.”
