Russell Brand has announced he has filed for divorce from US singer Katy Perry after 14 months of marriage.

The comedian filed divorce papers in the Los Angeles Superior Court, citing irreconcilable differences.

In a statement the 36-year-old said: "Sadly, Katy and I are ending our marriage. I'll always adore her and I know we'll remain friends."

The announcement comes after speculation in the press about the state of their relationship.

The couple spent Christmas apart. Brand was pictured in Cornwall, whilst Perry spent it with friends in Hawaii - neither was wearing a wedding ring.

The couple met in 2008 and married in October 2010 at a resort inside a tiger reserve in India.
