Russell Brand filed divorce from singer Katy Perry on Friday after just 14 months of marriage.

“Sadly, Katy and I are ending our marriage. I’ll always adore her and I know we’ll remain friends,” Brand said in a statement.

Brand filed court documents citing “irreconcilable differences” in Los Angeles on Friday, according to reports.

The legal documents referred to Perry by her given name Katheryn Elizabeth Hudson and showed that there are “community property assets,” which probably means that there was not pre-nuptial agreement in place.

There were rumors that the couple had martial problems when they celebrated Christmas apart this year. Brand, 36, spent the holiday in the UK while Perry, 27, spent the Christmas with friends in Hawaii.

Perry has not made a comment about the split. She was not wearing her wedding ring when she was photographed in Hawaii on Dec. 25.

Brand’s announcement is surprising because just four weeks ago he had declared that his relationship was going strong.

“I'm really happily married. I’m married to Katy. Perpetually, until death do us part was the pledge. I’m still alive,” Brand told Ellen DeGeneres on her show.

Perry had also told DeGeneres that she “would love to have children” with Brand.

A source told US weekly on Friday the couple recently got into a “massive fight” and Perry had said to Brand that she was going to do her “own thing”.

Perry and Brand began dating in 2009, and just four months later brand proposed on New Year’s Eve and they were married in October 2010.
