Weston Cage, the oldest son of Nicolas Cage, has filed divorce papers in L.A. County Superior Court last week, looking to end his troubled marriage to singer Nikki Williams.

Weston is citing irreconcilable differences as the reason for the split. He has asked the court not to award any spousal support to Nikki, and wants her to pay for his legal fees.

Nikki wrote on her Facebook page: 'The single life is perfect,' and has already dropped the 'Cage' from her profile.

Meanwhile, Weston wrote on his Facebook page: 'WELL ITS OFFICAL. THE DIVORCE IS SETTLED! 'LADIES, DADDY IS BACK ahahahhahahaahh. Oh god! its on.'

Weston appeared in Cage's film Lord of War as Vladimir, a young Ukrainian mechanic who quickly disarms a Mil Mi-24 helicopter. He also appeared in a vampire film Raven in 2009.
