Paula Patton has filed for divorce from her estranged husband Robin Thicke after eight years of marriage, media reports said Wednesday. The “Mission Impossible - Ghost Protocol” actress reportedly cited "irreconcilable differences" as the reason for their spilt.

Patton reportedly filed for divorce in Los Angeles on Oct. 3 and requested for joint custody of their 4-year-old son, Julian Fuego. Patton, who married Thicke in 2005, gave birth to their son in 2010. Patton reportedly listed the date of her separation with Thicke as Feb. 21. The 37-year-old singer-songwriter was accused of cheating on his wife several times.

"We will always love each other and be best friends, however, we have mutually decided to separate at this time,” Patton and Thicke reportedly said, in a statement, in February, while announcing their separation.

However, a source told Us Weekly that their split was not a mutual decision as it was being described by the two stars.

"Robin wanted to save their marriage, but it was Paula's choice and she ended it," a source told Us Weekly, at the time. "Robin does not want this divorce."

Thicke made several efforts to woo back his 38-year-old estranged wife. In June, Thicke named his seventh studio album after Patton. Thicke also apologized to her on-stage at the BET Awards 2014.

"I'd like to dedicate this song to my wife, and say, 'I miss you, and I'm sorry.' This is called 'Forever Love'," Thicke reportedly said, before performing the song.

In April, Thicke said in a deposition for an unrelated legal case that his serious drug abuse was the reason behind the break-up.

“When your wife [Paula Patton] leaves you, it gives you a good reason to be sober," Thicke reportedly said.

In May, Patton reportedly addressed her separation from Thicke saying: "[Robin and I] have known each other since we were teenagers... All I can tell you is there's a deep love there --always was, and always will be."
