See the Most Shocking Things Naya Rivera Revealed in Her Memoir ‘Sorry Not Sorry’

She had sex with a married man in Abercrombie, after the store was closed.

When Naya was 19, she worked at Abercrombie with a guy named Greg, who was 30. One night after the store closed and they were there late folding clothes, "Greg started coming onto me… I was more like 'oh well' than 'oh wow,' but figured why the hell not?" she wrote.

It was later that she found out he had a wife, whom she called to tell about what happened.

Naya was in London with Big Sean when she found out about Cory's passing.

"This also became a defining moment in my relationship with Sean — I started to realize that I was dating an incredibly selfish person. I shook Sean awake and told him that Cory had just died. He just said, 'Oh man, babe, I'm really sorry about that,' and rolled over and went back to sleep," she wrote.

Afterwards, she called her costar Kevin McHale and they sat on the phone together for hours and cried.

She dated Mark Salling for THREE YEARS.

Mark's team thought it would be better if he was "single," so they kept their relationship a secret. Eventually, he broke up with her because all they did was argue all the time.

In her memoir, Naya explains how thankful she is that things ended because, well, he ended up being arrested for allegedly having child porn on his computer. "My son's nanny actually told me about it when the story broke. I can't say I was totally shocked, but still W-T-F?!" she said.

Remember that time Naya reportedly keyed Mark Salling's car after she found out he was cheating? Well… that's not exactly what happened.

While Mark was away on a trip, Naya found out that he was indeed cheating on her. So she called up her friend and they "bought dog food, Coca-Cola, eggs, and bird seed, and then dumped all that [expletive] all over his car." But they never keyed it!

Remember that infamous Rolex tweet? Well, that's what ended her relationship with Big Sean.

After Naya couldn't find the Rolex Big Sean had given her when they first started dating, she called him up and asked him what happened to it. After a lame excuse as to why he took it from her, she had "one of my weakest moments OF ALL TIME" and tweeted about it.

"He responded in kind, but in a way, way bigger fashion: he had his publicist release a statement saying the wedding wasn't just postponed, but that he'd decided to call it off," she wrote. "So I learned that I was no longer getting married from THE INTERNET, and at the same time as the rest of the world."

Big Sean wrote "I Don't F— With You" About Naya after she begged him not to write a song about her.

"And now I have a rap song about me. That's almost as good as a star on the Walk of Fame, right?" she wrote.

Lea Michele apparently was the queen of hissy fits on the Glee set, and made Tim Conway's granddaughter cry during her set visit!

While they were filming the second to last episode of season five with Tim Conway, Lea got fed up with his improvising. "Instead of just rolling with it, she kept interrupting. 'So, like, um… are we going to do the scene as it's written now?'" Naya revealed.

"He'd even brought his granddaughter to the set because she was such a Glee fan, and she ended up crying because she couldn't understand why someone was being a b—- to her grandpa."

Yikes! To make matters worse, Lea ended up locking herself in her trailer and refusing to come out.

Remember those rumors that Naya Rivera was fired from Glee? Well apparently Lea Michele leaked that info to the press.

After Lea locked herself in her trailer and refused to come out, Naya got into a heated argument with Glee creator Ryan Murphy. And while he went MIA on her during their hiatus, he didn't have any plans to fire her.

"I guess you can throw a b—- fit, lock yourself in your trailer, and stall production, yet still allegedly find the time to leak stories to the press," she wrote.

Naya didn't actually get married to her husband Ryan Dorsey on the day she was supposed to marry Big Sean.

She dated Ryan before she met Big Sean, and he reached out to her after their breakup — which is the start of their love story. And while their wedding was admittedly "fast tracked," Naya denies that her already-planned wedding with Big Sean had anything to do with it.

"Sean and I were supposed to get married in Santa Barbara, not Mexico, and Ryan and I didn't get married on the same date — we got married on Ryan's birthday. I bought a Carolina Herrera dress for my wedding with Sean and wore Monique Lhullier when I married Ryan," she wrote.

She had an abortion while she was on Glee and never told her now-husband Ryan Dorsey about it.

After they reconnected following her split with Big Sean she told him about it. He was hurt that she felt she couldn't go to him with the news before.

Her "arch-nemesis" in high school was Nazanin Mandi, Miguel's fiancée.

"When we were teenagers, she was two grades ahead of me at Valencia High. She got to sing at every damn pep rally! C'mon, girl — give a freshman a break!" she wrote.

She got a boob job as soon as she turned 18.

"People have a lot of opinions about plastic surgery, but more than ten years after I got my boobs, they still make me happy when I look in the mirror. It might have even been the best $8K I've ever spent," she admitted.
