“Glee” alum Naya Rivera has some shocking revelations in her memoir, “Sorry Not Sorry: Dreams, Mistakes, Growing Up.”

In her book, Rivera said that she found Ariana Grande spending some time with her then-fiancé Big Sean at the latter’s house in Los Angeles. At that time, Rivera had been feuding with the rapper for the past five days, and Big Sean told the actress/singer that he didn’t want to see her. “Well, a—hole, I’ve got a key to your house. I walk in, go downstairs, and guess what little girl is sitting cross-legged on the couch listening to music? It rhymes with ‘Smariana Schmande,’” she wrote.

Even though Rivera didn’t actually name Grande as the woman she saw at Big Sean’s house, US Weekly reported that Grande and the rapper immediately got into a relationship after he and Rivera ended theirs. However, Grande and Big Sean’s relationship didn’t last very long either. What's even more surprising is that Rivera said that even though she was the one who saw another woman at her ex-fiancé's house, it was the latter who actually called off their wedding.

“I learned that I was no longer getting married from the internet, and at the same time as the rest of the world. Not only were we no longer getting married, but apparently we weren’t even together anymore,” she wrote.

In other news, Rivera also shared in her book that she struggled with anorexia while she was growing up, according to Cosmopolitan. While she was still in school, Rivera’s weight dropped to just 98 pounds. She also passed out during her P.E. class due to dehydration. “I gained 15 pounds and never looked back,” she said. Additionally, Rivera confirmed that she got an abortion when she was still part of “Glee.” At the time, she had just broken up with her current husband Ryan Dorsey. Unfortunately, River didn’t name the person who fathered her baby.
