Anna Faris does not believe that husbands and wives should be best friends.

In a new essay, Faris revealed that she did not think of her ex-husband Chris Pratt as her best friend even when they were still married because she believes partners and friends serve a different purpose in her life. She explained that maintaining a group of close girlfriends is as valuable as having a mate.

"I was once told that I didn't need a tight group of girlfriends because Chris should be my best friend. But I never bought that," Faris wrote in an essay published in Cosmopolitan. "The idea of your mate being your best friend—it's overhyped. I really believe that your partner serves one purpose and each friend serves another."

Amid her split from the "Jurassic World" star, Faris is glad that she has a group of female friends that she could talk to and lean on. Otherwise, she would have been alone after her separation from Pratt. "Today, I'm lucky to have a handful of women I count as confidantes," Faris confessed. "Among them, Allison Janney, my costar on 'Mom,' Meghan, a friend from my hometown of Edmonds, Washington, and Kate, a dear childhood friend who I probably have nothing in common with anymore—at least from an outsider's perspective—but who totally gets me because ... history."

The "House Bunny" star declined to rank her friends as it might put pressure on them. Faris also said that she believes that she can maintain an intimate relationship with different people in different ways.

Aside from expressing on her thoughts about partners and best friend, Faris said in another statement that her estranged husband didn't have her back. "Life is too short to be in relationships where you feel this isn't fully right or somebody doesn't have your back, or somebody doesn't fully value you," the "Scary Movie" star said, before urging other women to acknowledge their own worth and independence.

Although Faris has suggested that her relationship with Pratt had not been perfect, the exes remain amicable after their split. Faris' dad, Jack Faris, said that the ex-couple still love each other and are committed to their 5-year-old son, Jack, who was named after him.

Meanwhile, Faris is set to release her memoir on Oct. 24. According to the mom-of-one, she feels nervous about the release of her book because it is very intimate to her.
