Pop singer Britney Spears is reportedly ready to have another baby as soon as her residency in Las Vegas comes to an end.

The Toxic hitmaker, who is a proud mother of Sean Preston, 8, and Jayden James, 7 with ex-husband Kevin Federline, previously admitted she is eager to have a daughter with her new boyfriend, David Lucado.

Despite rumours that she is in talks to extend the contract for her concert series until 2016, Britney was reported saying that she can't wait to start a family with David Lucado.

Acoording to website RadarOnline.com: "Britney cannot wait until the Vegas show is done because she wants to start a family with David. She says she will get pregnant as soon as the show is finished!

"David is always with her in Vegas and they act like an old married couple together. He is really good with her kids and has taken to the father role pretty easily."

The 32-year-old singer started dating David, who is a researcher at a law firm, in March 2013, just two months after ending her engagement with Jason Trawick.

The Criminal singer admitted earlier this year she would love to have more children.

She said: "I would really like to have another baby, a girl. I think she would be like a mini-me. I think it's going to be crazy. I'm not going to feel as alone in the world anymore. I'm going to feel like I have a second person, like, that's me."
