In new tell-all DYAN CANNON rips the lid off those CARY GRANT gay rumors and reveals how he forced her to take drugs!

Cannon reveals the intimate deets of her dysfunctional life with the Hollywood legend despite their 33 year age difference in new memoir "Dear Cary: My Life with Cary Grant."

“He melted me,” she told Fox 411. “He was the most charming, suave and wonderful man in so many ways. He was older and wiser and he changed my whole way that I dressed, the way I looked, the clothes I bought, the books I read, the thank you notes I would write and I thought it would make him happy if I did those things. The thing I wanted most in my life was to make him happy.”

Cannon admitted she took LSD with Grant in an attempt to strengthen their relationship but she later flipped out as their marriage fell apart.

“It made me crazy,” Cannon confessed. “I’m lucky to be alive today. I went nuts. I lost it. I climbed out a window in the middle of the night in the pouring rain thinking I was doing something very natural. I ended up in a mental institution.”

Cannon, who bore the suave leading man a daughter, Jennifer, in 1966, also addressed the long standing gay rumors about Cary.

That part of our life was very fulfilling so I don’t know,” she said. “I never saw any indication of it.”
