Looks like lines of truth were seriously blurred with yesterday’s menage a trois madness involving Robin Thicke and Paula Patton’s marriage! Robin is threatening to take legal action over yesterday’s report that he and his actress wife were involved in a “three-way relationship” with a massage therapist. The duo’s lawyer Howard E. King has allegedly sent a letter to Star Magazine and OK! threatening legal action, after they reported that the hubby and wife team were in a polyamorous tryst that went sour because Robin fell for the other woman!
