Britney's sister expecting second baby?

Reports that Jamie Lynn Spears is pregnant with her second child have been refuted by an "unimpeachable source".

US reports had claimed that Britney's little sister was pregnant less than four months after the birth of Maddie Briann.

However, a source told TMZ that there is no truth to the rumours surrounding the 17-year-old and her fiancé Casey Aldridge.

Spears's mother Lynne recently told how she learned of her daughter's pregnancy at the age of 16 in a note, admitting she has taken responsibility for both of her daughters' woes.
