Britney Spears has revealed that she would love to have a baby with boyfriend David Lucado.

The singer is apparently counting down the days until her Las Vegas residency is over and she can settle down and have another sibling for sons Sean Preston and Jayden James.

“Britney cannot wait until the Vegas show is done because she wants to start a family with David," an insider said.

"She says she will get pregnant as soon as the show is finished."

According to reports, David has been supporting Britney during the residency which is to last for two years, and is a regular face on the scene.

“David is always with her in Vegas and they act like an old married couple together," the insider continued.

“He is really good with her kids and has taken to the father role pretty easily."
