Britney Spears is to appear in a second series of her reality show Britney and Kevin: Chaotic, in a bid to end rumours her marriage to Kevin Federline is on the rocks.

Britney and Kevin: Chaotic follows the singer in her everyday life and Spears hopes extending the show will end speculation surrounding her private life.

The last few months have seen the couple plagued by press reports heralding an imminent divorce, as well as criticisms of the "Toxic" hitmaker's parenting skills.

The 24-year-old, pregnant with her second child, says, "I know that things are fine, but this show will put paid to those rumors finally."

Britney has now decided to put the record straight in another fly-on-the-wall series.

Memorable moments in the first season include Spears bragging about her lengthy lovemaking sessions, and begging her husband-to-be for sex.
