Spears made headlines in January with her impulsive Las Vegas marriage to her childhood friend Jason Allen Alexander. That marriage was annulled after two days, but this time Spears seems to take the prospect of saying �I do� seriously. 

Federline and Spears have reportedly been dating for just two months.

Last week the British tabloid News of the World reported that the engagement is due to the fact that Spears is pregnant and is expecting around Christmas, according to a "Spears insider". If this is true it is not the only baby that Federline is reportedly expecting. According to Herald Sun, 27-year-old actress Shar Jackson says that she is 8-months pregnant with Federline's child, who is also reportedly the father to her 2-year-old daughter. The Herald reports that Federline and Jackson were also engaged until a few weeks ago. 

After keeping quiet on the matter for a week Spears broke her silence to People Magazine. "Marrying Kevin was the last thing I was thinking about doing," Spears told People in its July 12 issue. "But then I said, You know what? This is my life and I don't care what people think. I'm going to get married. I'm in love with him."

She also addressed the issue of Kevin's children and the rumors that she was expecting. "I plan to meet his daughter," Britney said. "I love little ones. I think the situation is good."

"I'm not pregnant. But I definitely want to have some kids. I see myself with four or five." She added: "We're starting with a dog. I just got a Maltese named Lacy."
