Britney Spears may seem to have it all - wealth, fame, two handsome sons, and a new contract in Las Vegas for two more years. Despite all that she have right now, the 33-year-old singer still wants to have one more thing -another baby.

A source known to be close to the pop superstar told Radar Online the one thing that Britney really wanted to have - a baby girl."A daughter is the one thing that she feels is missing in her life," the insider says.

Although the mother of two boys, Jayden James, 8, and Sean Preston, 9, has extended her contract for Las Vegas residency "Piece of Me" for two more years, the source explained that Spears is already preparing her baby plans. "When Britney is done with her Las Vegas residency she is going to have a baby girl," the source told Radar.

The pop star's last known relationship was with Charlie Ebersol. However, US Magazine said that Britney and her 8-months boyfriend called it quits in June 2015. This made Britney's single, one more time.

Despitebeing single, the source confessed to Radar that the superstar now realized a man is not necessary to come into her life just to have another kid. "And if she has to, she will use insemination to do so and will have this child on her own!" the source added.

Britney Spears first mentioned her plans of having a third child in an interview with InStyle magazine back in 2013. This was right after her break up with ex-fiance JasonTrawick.

Spears may not be lucky enough in finding her one true love, but some fans are very hopeful that she will have a another kid in the future. Does Britney really need a third child? Will this make her happy for the rest of her life?
