The former Desperate Housewives actress believes that all women should have someone close who they can confide in.
She told LOOK magazine: "I think every woman should have a close circle of friends to talk to."
Longoria also revealed that she enjoys having a friend who is in the fashion business.
She said: "People keep saying they're envious of my friendship with Victoria Beckham but we're pretty boring. We just talk about normal girl stuff and I borrow her clothes."
Although she loves to dress up and borrow Beckham's glamorous clothes, Longoria added that she feels at her best when she is dressed down.
The actress, who has recently split from Eduardo Cruz, added: "I feel sexiest probably right after a shower when I'm just in my sweats without make-up.
"I have to wear so much all the time because of the cameras, so I just want it all off when I get home."
