Isn't it ironic? Britney Spears is a sex symbol to some folks, but the mom of two dreads the day she'll have to tell her sons about the birds and the bees.

Sean Preston and Jayden James are 4 and 3, so the singer better start prepping or let her boys' daddy, Kevin Federline, field their questions. Have you ever been nervous to have a conversation with your kids? What was the topic?
