Paula Patton files to divorce Robin Thicke, little about it is blurred

Paula Patton has moved to formalize her split from “Blurred Lines” crooner Robin Thicke, and there’s little about it that’s blurred.

The actress-model filed the divorce petition last Friday in Los Angeles Superior Court, citing irreconcilable differences, according to court documents obtained by the Los Angeles Times.

Patton, 38, who has been married to Thicke for nine years, is asking for joint physical and legal custody of their 4-year-old son, Julian Fuego Thicke.

The “pro per” filing -- that’s shorthand for the legal term meaning she’s representing herself -- formalizes the couple’s separation, listed as happening Feb. 21, 2014. The pair announced their plans to go their separate ways just days after that date.

As of Thursday morning, Thicke had yet to file his response to the petition. Patton’s indicated that their division of property would be decided at a later date.

“We will always love each other and be best friends,” the couple said at the time in a statement to People confirming their mutual decision to separate.

Thicke, 37, and Patton had been longtime loves, with Patton meeting him at age 14. They wed on June 11, 2005.

Despite the joint statement, however, Thicke appeared blindsided by their decision to break up and since February has made several gallant public attempts to win back his wife -- even titling his latest album “Paula” as an apology.

He also maintains that he wasn’t unfaithful, despite reports to the contrary.

“That’s not why we’re apart,” the R&B singer said during a July radio interview. “We’re apart because we just couldn’t be together anymore.... There’s a hundred different reasons; there isn’t just one. There’s a long list.... I got a little too selfish and a little too greedy and a little too full of myself.”

The son of actor Alan Thicke is currently embroiled in litigation with the estate of Marvin Gaye involving claims that the 2013 hit “Blurred Lines” has more than a passing resemblance to Gaye’s 1977 song “Got to Give It Up.”

In an April deposition that was unsealed last month, Thicke admitted that he was high on Vicodin and drunk during the recording of the song, saying he contributed little besides his lead vocals to the recording.

Wonder if it’ll affect album sales. Follow me on Twitter @NardineSaad.
