Susan Lucci, Christie Brinkley, Brooke Shields and more perform 'Celebrity Autobiography' in the Hamptons

Susan Lucci, Ralph Macchio, Debbie Harry, Christie Brinkley and Brooke Shields shared the stage at Guild Hall in East Hampton Friday night for a performance of "Celebrity Autobiography."

Brinkley's three kids, Alexa, Jack and Sailor, came out in support. The supermodel found herself a little rockstar-struck, snapping photos of her firstborn Alexa Ray Joel, with legend Debbie Harry. "Both Debbie and Alexa have been playing the Carlyle, so I was, like, I have to get this shot."

"Alexa drove all the way in from the city and she's turning around and driving right back ... I'm a very lucky mom," says Brinkley.

Christie, along with fellow leading ladies Susan Lucci and Debbie Harry, stole the show with their on-stage sisterhood, reading "Kardashian Konfidential." (Christie played Kourtney, Susan was Kim and Debbie portrayed Khloe.)

As far as allowing reality-show cameras in her Hamptons house, she was quick to reply, "No, no. Not going to happen!"

Brinkley' s book, "Timeless Beauty," which is full of tips and tricks, comes out November 10th. The supermodel's best beauty secret: "Definitely I would say that being happy and joyous is really good because at the very least a smile is an instant face-lift, picks up your spirits and picks up your face!"

Susan Lucci, whose series "Devious Maids" ends Monday night after three seasons, says that the cast and the fans are all hoping for a fourth season. But, for now, she's finally taking a little summer vacation.

"My husband is from the Austrian Alps -- he thinks that the Hamptons is the most gorgeous place on the planet in the summer. He doesn't want to go anywhere right now."

Taking a page out of Susan's book, she says the key to having a long, successful career is  "to simply love what I do and I feel really lucky to do what I love to do, that's it."

Ralph Macchio did his best Bieber on stage. Backstage, he talked about the difference growing up in the spotlight these days.

"The biggest difference, I get asked that question a lot, is social media," he says. "It's the fact that everyone with a phone is the paparazzi. It was different back then ... you knew you had a few seconds to kill a story -- not that I had any stories I needed to kill! Although I could have used a couple of stories," he joked. "Now within 10 seconds it's around the world."

Ralph is on dad duty next week, bringing his son Daniel back up to Boston College.

"We're filling out the itinerary and getting the minivan and heading up to Boston. I'm going to miss him ... its been a nice summer together, but time to get busy, back to it!"

Debbie Harry was happy to read the autobiographies of others on stage but when it comes to her own

"Doing this makes me think, well maybe I shouldn't!"  Aw, Debbie, we're sure you have some good stories to share! "I hope so, I hope I can dig some out, if I can remember them!"
