Britney Spears will not be walking down the aisle with her fiance until after she gives birth.

“Britney and Sam are being playful with each other, and they are not married. She is going to wait until after she has the baby to focus on that and she will have 9 months to plan her dream wedding now. Sam and Britney have been calling each other husband and wife since they got engaged. She will continue to do so until they are married, which will not be kept a secret,” a source said to Hollywood Life.
