Open Marriages: Hollywood’s Worst Kept Secret?
Robin Thicke and Paula Patton

From what started as a consensual three-way relationship with a masseuse the couple came across, turned into a stab in the back affair by Thicke and a divorce filing from Patton. The successful couple were even high school sweethearts and had been best friends since their teenage years.
Even worse, after Thicke confused the rules of the three-way, he was allegedly even caught cheating with a 23-year-old while Paula was in the room with them. While on while being interviewed on Hot 97, Thicke copped to his mistakes, saying, “There’s a long list…I changed, and I got a little too selfish, a little too greedy and little too full of myself”. We guess not even an entire album dedicated to getting Paula back could make her forget that Thicke got a little too greedy.
Chris Robinson and Kate Hudson

Wilder than her ex-husband and singer of the Black Crowes, Chris Robinson, actress spawn of Goldie Hawn, Kate Hudson, reportedly wanted an open marriage. Ironically reports came directly from her mother and mother’s partner (famous actor Kurt Russell) who Kate refers to as “Pa.”
To be free to sleep with whatever celebrities she wanted, she decided to divorce Robinson although he is the father of one of her sons (Ryder) after six years. Since their divorce, Robinson has remarried and Hudson has been linked to several celebrities, but the two seem to co-parent Ryder in peace despite the ending of their marriage.
