This is a new development in the Robin Thicke Paula Patton split. According to Star the couple was involved in a consensual three-way relationship, but the actress had enough when she started a two-person affair with Thicke!

The third party is referred to as Jasmine, a massage therapist, and the affair had been going on for two years. One day Patton walked in on the woman and her husband and that's when she called quits.

"Paula felt betrayed and humiliated by both Robin and Jasmine," said the insider, who Star claim took a polygraph test. "These were two people she thought she could trust the most, but in the end everything backfired on her."

Thicke allegedly did not understand why his wife got upset.

"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 insider explained.

The "Mission Impossible: Ghost Protocol" star gave her husband another chance, yet could not put her doubts behind her. They announced their split in February as Thicke tried to win her back.

According to The Daily Mail, both parties have stopped wearing wedding rings but neither has begun divorce proceedings. Patton was seen getting close with costar Jeremy Renner at the Independent Spirit Awards.

This comes on the heels of Thicke's father Allen praising his strength post-split.

"I hope whatever they decide to do will make them both happy. That's the key thing. You want your kids to be happy. They're strong, smart and talented people and they'll make great decisions." He told E! News.

Thicke made headlines last year with controversial hit "Blurred Lines." He also performed a risqué performance with Miley Cyrus at the MTV Video Music Awards.
