AceShowbiz - Pamela Anderson put on weight while writing her memoir. The 55-year-old actress opened up on a "physical reaction" to penning her new book "Love, Pamela" because she gained a "puffy suit of armour" even though her regular diet regime didn't change.

"I went through kind of a crazy time writing the book. I started writing my book and I put on like 25 pounds, Crazy! I look back at it and I see how it was the book process because as I wrote my book, I didn't change too much," she said.

"I mean, I was drinking earlier with the husband and stuff but I lost it all at the end of my book. It was crazy, it was crazy! I had a physical reaction to telling my story. "

"It was almost like I was hanging on to something - It was a protective… my puffy suit of armour. I don’t know what it was - I was thinking it was some kind of protection. It wasn't like I was eating any different, I'm vegan, I eat nuts and berries, you know, I don't eat a lot. But my body was changing!"

The former "Baywatch" actress - who split from bodyguard Dan Hayhurst in January 2022 after just over a year of marriage but was previously married to Motley Crue rocker Tommy Lee as well as Kid Rock, Rick Salomon, and Jon Peters - added that she was a "mess" when writing the book but enjoyed being able to "peel back everything" for the tome.

Speaking on "The Howard Stern Show", she added, "I was a mess at that time, so I kind of liked that I peeled back everything, No make-up, nothing like that, and I thought, 'You know what? If you like me like this - if you like me at my worst, maybe you like me.' "
