Giuliana Rancic opened up about her love experience with Jerry O'Connell in her new memoir "Going Off Script: How I Survived a Crazy Childhood, Cancer, and Clooney's 32 On-Screen Rejections". She wrote in her book that her ex-boyfriend cheated on her twice, first with Spice Girls' star Geri Halliwell and second with "X-Men 2" actress Rebecca Romijn.

The "Fashion Police" host said she was giving O'Connell another chance when she found out that he was cheating on her with Halliwell, but later she learnt that he was flirting with Romijn while at Maxim's 100 Hottest Women Party. "Little did I know he was in the VIP area, talking to Rebecca. As a prelude to feeling up Rebecca," she said.

She wrote in her memoir, "I was being two timed." She continued, "He said 'Yeah, I know. I'm so sorry. I don't know what happened.' He has as much emotion as the customer service representative who tells you your bags missed the flight."

O'Connell did not respond to Rancic's phone call after that. Rancic decided to confront him directly by coming to his home. However, he gave a disappointing response. "Nope. Sorry, home girl. Things change, but you take care, OK?" so Rancic recalled how O'Connell ended their relationship.

In 2007, O'Connell ended up marrying Romijn while Rancic married Bill Rancic in the same year.
