Christian Slater has begun divorce proceedings to end his five-year marriage to Ryan Haddon, the Internet Media Database reported.

The pair split in January, during Slater's stint in the play "One Flew Over The Cuckoo's Nest" in London's West End theatre, amid rumours that Haddon was sick of the actor's non-stop partying.

TV Producer Haddon was also keen to move back to Los Angeles with their two young children, whereas Slater wanted to stay in Britain - according to reports.

Just last week the "True Romance" star expressed his determination to reconcile with Haddon, insisting, "I am naturally extremely keen to make sure everything works for the best."

But the actor filed a divorce petition citing irreconcilable differences.

Slater's publicist, Evelyn Karamanos, said in a statement: "The mutual decision was reached amicably and they remain committed to raising their two young children together. They ask for the respect of their privacy at this time."
