Jamie Lynn Spears showed off her big belly as she cuddled up to a puppy at her friend's house in Mississippi. Can't hurt to get a little parenting practice in with a furry buddy, right? Jamie Lynn has a little less than 2 months to go before bringing her baby girl into the world, which means it's baby shower time! Her mother Lynne will be hosting the party in Kentwood on Saturday with a special guest star — Britney! Apparently Britney had to beg Jamie to let her be by her sister's side, but in the end, her dad decided it was best to let the sisters reunite and celebrate the big day.
