While cheating rumors plagued Paula Patton’s marriage to singer Robin Thicke, the plot has thickened even more. The couple is now rumored to have split because Thicke had an affair with a woman the two were engaging in consensual threesomes with.

According to Star magazine, Patton, 38, and Thicke, 36, had an open relationship, and engaged in threesomes with a massage therapist, "Jasmine," for two years. Her true identity is being concealed. Thicke reportedly strongly encouraged Patton to go along with that lifestyle. “Robin pushed Paula to allow Jasmine into the bedroom with them in order to spice up their sex life, and she reluctantly agreed in an attempt to keep him happy,” the source explains. However, Jasmine reportedly carried on a romantic relationship with Thicke one-on-one, which Patton didn't like.

The magazine even claims Patton walked in on the two in the act. Though she forgave him and gave their relationship another shot, she was not able to look past his actions, and decided to end the marriage.

"We will always love each other and be best friends, however, we have mutually decided to separate at this time," the couple said in a joint statement to People magazine in February. 

It has long been speculated Patton and Thicke had an open marriage, especially after Patton had no reaction when photos surfaced of Thicke in compromising positions with women.

Paula Patton and singer Thicke married in 2005 after dating throughout their teenage years.  Thicke said in an interview last year that he knew right away that Patton was the woman for him. “I knew she was special the night I met her,” and years later, their love is still ironclad, he says. “As a relationship progresses, you fall in love again in so many deeper ways. You realize that you need each other and you can’t live without each other.” They now have a 3-year-old son, Julian.
