Gwyneth Paltrow isn't immune to serial cheater after all. The actress known for her Pepper Potts portrayal in the first two "Iron Man" films got candid about her past love life in an interview for the March issue of Harper's Bazaar, revealing that she knows what it feels like to be betrayed by a boyfriend.

"I had a boyfriend who used to cheat on me all the time," confessed the former girlfriend of Hollywood actors, Brad Pitt and Ben Affleck. She went on to describe her younger self as someone who "was quite naive", further admitting, "I knew on a cellular level, but I bought his story."

Despite the betrayal, Paltrow does not condemn those who have had affairs. "The older I get, the more open-minded I get, the less judgmental I get," she explained. "Life is long. I have friends who I love and admire who have had an affair. When I was younger, I would have said he's a terrible person or she's a terrible person. But who made these laws?"

The 39-year-old actress additionally pointed out, "I think you do fall in and out of love and you just keep going, and every time you go through a really difficult phase, you rediscover something new and it just gets better. We've been married for more than eight years now, and we're still into it."

Speaking about husband Chris Martin, Paltrow described the Coldplay frontman as "very communicative," noting, "which is rare for a British man." She also shared her secret in making her marriage work. "I want to maintain my marriage and my family, so I have to be here when he comes home," she said.

Talking about a marriage advice she gave to a girlfriend of hers, the "Contagion" actress claimed to have told her, "You have to compromise." She continued on, "Gloria Steinem may string me up by my toes, but all I can do is my best, and I can do only what works for me and my family."
