Britney Spears and Kevin Federline are to renew their wedding vows, it has been claimed.

The couple - who are expecting their second child together - are said to be so fed up with the negative rumours surrounding their personal life they are planning to head down the altar again to stop the speculation.

Britney and Kevin - who have a nine-month-old son, Sean Preston, together - have reportedly planned an intimate ceremony on the Hawaiian beach of Maui next month.

A source was quoted in Britain's Daily Star newspaper as saying: "They want to stop all the gossip."

The couple - who married after a whirlwind romance - have been hit by rumours their marriage is on the rocks due to Kevin's frequent partying.

However, Britney, 24, has denied their relationship is in trouble, and recently announced the couple are planning to appear in a second series of their hit reality show Britney and Kevin: Chaotic - to prove their marriage is rock solid.

She said: "I know that things are fine, but this show will put paid to those rumours finally." (source:Bang! Showbiz)
