It's the ultimate on-screen sisterhood -- four best friends sharing their deepest secrets about life and love. Now, "Extra" is learning that the bond of friendship between the "Sex and the City" ladies is even tighter than we'd known!

In the final season of the TV show, Samantha (Kim Cattrall) delivered devastating news of her cancer -- and now, in a strange coincidence, Cynthia Nixon reveals details about the night a year and a half ago when she told best friend Kristin Davis of her breast cancer.

Davis recalls, "She sits me down in Cynthia fashion and says, 'I have something to tell you. I have breast cancer.'" After a lumpectomy and radiation treatment, Cynthia is now celebrating one year cancer-free -- but says she'll never forget the way her friend reacted. "She stood up on her chair and I couldn't get her to come down until I told her everything I was doing and assured her everything was going to be okay," says Nixon.

The two friends celebrate their sisterhood on the big screen when "Sex and the City" opens May 30th.

"Extra" is speaking exclusively with country crooner Kenny Chesney as he discusses his painful onstage mishap in South Carolina last week during a performance on his "Poets and Pirates" tour. As to the cause of the accident, Kenny says, "I had my foot over the side of the elevator. As it was coming up, the elevator sort of went flush with my foot in the middle and no one could do anything." He adds, "It took them awhile to get to me. It's a pretty vulnerable position to be in."

Chesney spent 30 excruciating seconds down on the stage, struggling with the pain in his foot, and admits that time felt like an eternity. Although he states, "I was literally in shock for two or three songs," the singer did not let the injury prevent him from finishing his show. "I knew those people [in the audience] had been out there all day," says Chesney, "pure adrenaline is what got me through the show."

Doctors have given Kenny the green light to continue his tour, which you can catch -- bruised foot and all -- through September!

Oscar-winning actress Gwyneth Paltrow is talking about her battle with post-partum depression, which she endured after the birth of her second child, Moses, in 2006. "I didn't know I had it until after it was over," Paltrow told Us Weekly. "I just didn't know what was wrong with me."

Paltrow reveals the problem in the May issue of Vogue, and suspects the depression stemmed from not undergoing pre-baby acupuncture treatments, like the ones she received while pregnant with her first child, 4-year-old daughter Apple. After giving birth to Moses, Paltrow admits, "I felt really disconnected. I felt really down. Since the birth of her son, the actress stepped back from the Hollywood limelight to focus on her growing family. She returns in May's "Iron Man," and has finally found a balance between working and being a mom.

"She set out to be a wonderful actress," mother Blythe Danner told Us Weekly, "but motherhood is very important to her... and I think she's finding a balance."
