If there was any doubt left about whether or not the marriage between movie star Paula Patton and her popstar husband, Robin Thicke, was over, there isn't anymore. It was announced today that Patton has filed for divorce from Thicke, citing 'irreconcilable differences,' as the reason. The couple has a 4-year-old son and Patton is reportedly seeking joint custody for both herself and Thicke.

The couple separated earlier in the year and Thicke has made several public overtures to win his estranged wife back. Clearly, none of them worked. When the couple officially separated earlier in the year, they released a joint statement which stated: "We will always love each other and be best friends; however, we have mutually decided to separate at this time." Patton and Thicke had been married for nine years.

Thicke performed at the 2014 Grammys earlier this year, and the event was the last public appearance for the couple before their subsequent separation. In his attempts to win his wife back, Thicke wrote songs for her and even released an entire album dedicated to Patton, though it only sold an unbelievable 530 copies in its first week.

Thicke admitted that he really didn't have much of a plan as he attempted to get Patton back, telling Good Morning America last summer: "I actually have no idea what I'm doing. I'm just kinda flying by the seat of my pants on this one."  

Thicke made headlines earlier this year for a different reason. The recording artist admitted lying about his writing credit on his hit "Blurred Lines." Thicke confessed while under oath during a plagiarism lawsuit that he was drunk and high during the recording sessions for 'Blurred Lines' and that Pharrell Williams actually wrote the entire song. The lawsuit has been filed by members of Marvin Gaye's family who have accused Thicke and Williams of copying Gaye's 1977 song "Got to Give It Up."
