While the actress was married to the Coldplay singer Chris Martin there was some speculation, that the two had an open relationship. One source even said that Paltrow didn’t care about Martin’s flings since she wasn’t the jealous type.
That’s the mature mindset we all need.
7. Kim Kardashian
When Kim Kardashian was dating Nick Canon, there were several rumors he asked her for an open marriage. Canon would expect her to remain faithful while he was allowed to fool around. Thank God she didn’t agree to this lifestyle!
