Gary Oldman's fourth wife Alexandra Edenborough has filed for divorce.

The 56-year-old actor - who was previously married to Lesley Manville, Uma Thurman and Donya Fiorentino - and the English jazz singer have been married since December 2008 but she has reportedly cited irreconcilable differences as a reason for their separation.

According to RadarOnline, Alexandra has listed the date of the pair's separation as TBD (to be determined) and asked the court to not award the 'Dark Knight' star spousal support, but she wants him to pay her lawyer fees and spousal support.

Gary previously admitted he ''wasn't proud'' to have married four times but was confident the 36-year-old brunette would be his last wife.

He said: ''I'm not proud to say that though. But I've had a few goes at it now, so I've probably learnt something from the first three.

''Practice makes perfect. Isn't that what they say? I'm not proud that this is my fourth marriage. But this is a good one. Hopefully, my last one.''

Gary didn't have any children with Alexandra but has three kids from his previous relationships, Alfie, 26, from his marriage to Leslie, as well as sons Gulliver, 17, and Charlie, 15, who he won custody of following his and Donya's divorce in 2001.
