Jennifer Esposito and Bradley Cooper stayed mum on their short-lived relationship, but it appears the "Blue Bloods" actress shows a darker side of her ex in memoir "Jennifer's Way."

Though she never officially mentions his name, the New York Daily News states it is easy to assume Esposito means the "American Hustle" star. Other experiences in the book include her battle with celiac disease, losing teeth on set, and having panic attacks.

The actress recalls a man asking her out with "a marching band of red flags" she ignored. Esposito did not find Cooper "necessarily attractive," but felt he was "funny, smart, cocky, arrogant, and a master manipulator."

She also adds "The Hangover" star "had a mean, cold side" and "his personality could flip on a dime." The pair quickly became a couple despite Esposito's doubts.

"I became very sad and I felt very alone," she writes, yet stayed in her relationship.

The star had a change of heart after a seminar at the Agape Spiritual Center in Los Angeles.

"Within days, my relationship hit an all-time low, and within a week it was over," Esposito explains. "Abruptly, rudely, and with the exact callousness that I'd come to expect from him."

After the split Esposito landed a role in "Samantha Who," which debuted in 2007. We know they were married from December 2006 to May 2007, so it would make sense she is talking about Cooper.

Cooper told Howard Stern in 2011 of the split, "It was just something that happened. The good thing, we both realized it. ... Sometimes you just realize it. It just wasn't right."

He is now rumored to be dating model Suki Waterhouse while Esposito is happily engaged to British model Louis Dowler.
