According to TMZ, the 34-year-old actor turned in his papers at the Los Angeles Superior Court and cited irreconcilable differences.
Sources claim that the “Two and a Half Men” star hesitated to make the split official because he wanted to give Miss Moore the first opportunity. After a year-long wait, Mr. Kutcher decided to take the divorce into his own hands.
Ashton and Demi tied the knot back in September 2005 and separated in November 2011. Since the split, the studly actor started a romantic relationship with his former "That 70's Show" co-star Mila Kunis.
