Britney Spears with baby, one more time

Pop Princess Britney Spears ended months of speculation last night by confirming on the David Letterman Show that she is pregnant with her second child.

The singer, who gave birth to her first child Sean Preston last September, was asked by Letterman, "So, we've established now that you are in fact pregnant, is that right?" to which Britney candidly replied, "Yes, sir."

The star then quipped, "Don't worry Dave, it's not yours."

Whilst the new arrival will be Britney's second child, the pregnancy marks child number four for husband Kevin Federline, who had two children with his former girlfriend Shar Jackson.
