Courteney Cox insists she has had her fair share of fashion and beauty disasters.

Speaking to PEOPLE recently for the “One Last Thing” page, the actress revealed she still isn’t very comfortable on a red carpet.

“I rarely look at a picture of myself and go, ‘Wow, that one really worked,” she says with a laugh. “I have to learn a new stance on the red carpet because I just haven’t gotten that down yet. I’ve been doing this for so long, I don’t know why I haven’t yet.”

Thinking back to her worst beauty disaster, Cox, 54, wasn’t a fan of her hairstyle in the 2000 movie, Scream 3.

“The fact that people say ‘forever on film,’ that is really true and it’s so bad,” she says.

Cox reprised her role as reporter Gale Weathers for the third installment of the film, and finding the right hair look wasn’t easy.

“I liked to change her hair every time,” the actress recalls. “I had these bangs and they were cut too short. At that time in my life, I wasn’t the kind of person who would say, ‘You know what? These are too short. We need to get new bangs.'”

Fortunately the actress used a hair piece rather than cut her own hair. “I was just like, ‘Oh, well, okay, oh God, they don’t look great,'” Cox adds. “In reality I should have said, ‘No, no, no we have to get new bangs.’ I did not stick up for myself and hence I look horrible. That was a big lesson—take care of yourself.”

Now Cox is producing the new Facebook Watch 20-part documentary series, 9 Months with Courteney Cox, which features a range of stories from people all over America as they self-document their journey through pregnancy.

“I was immediately drawn to this project,” the actress said. “As a mother, a woman and a producer, I was determined to bring these incredibly intimate stories to life in an honest and authentic way.”

The series, which will air twice a week with episodes on Tuesdays and Wednesdays, is the first project to come from Cox’s Hopper Productions partnership with AMPLE Entertainment.
