Naya Rivera reveals she found ex-fiance Big Sean at home with Ariana Grande before they broke up

Naya Rivera opened up in her shocking new memoir about how she found ex-fiance Big Sean at home with his future girlfriend Ariana Grande while they were still together.

''We'd been fighting for five straight days while he was traveling, and then on the one day that he was back in L.A., he said he didn't want to see me,'' the 29-year-old actress writes in the book. Well, a–hole, I've got a key to your house,'' Naya added about what she was thinking back then. 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.'''

Naya also opened up about how Sean broke off their engagement without telling her.

''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 said.
