E! News presenter Giuliana Rancic has ditched the script and spilled the beans in her new memoir.  Later this week Rancic's book Going Off Script - How I survived a crazy childhood, cancer and Clooney's 32 on-screen rejections will be released. Ahead of the book's arrival in stores, details of the presenter's relationship with actor Jerry O'Connell have been revealed. Rancic writes in her autobiography about a chance meeting with the Stand By Me actor in the W Hotel in San Diego, which quickly led to a relationship between the pair. It seems O'Connell wasn't the loyal sort at the time, however, with Giuliana discovering later that her beau was cheating on her with not one but two high-profile women! According to the Fashion Police presenter, she discovered that O'Connell was seeing Spice Girl Geri Halliwell behind her back. In an excerpt published via Page Six, Rancic wrote: "I was being two-timed...?" She then detailed O'Connell's reaction: "'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." Though she forgave the actor and gave the relationship a second chance, it wasn't long before Giuliana had another unpleasant discovery. While attending Maxim's 100 Hottest Women Party in 2004, the presenter spotted her boyfriend getting friendly with Rebecca Romijn. "Little did I know he was in the VIP area, talking to Rebecca," Giuliana wrote. "As a prelude to feeling up Rebecca." As for the eventual confrontation and breakup? This might be the worst line since Berger ditched Carrie on a Post-It. When Rancic went to his home to have it out, O'Connell said: "Sorry, homegirl. Things change, but you take care, OK?" O'Connell went on to marry Rebecca Romijin in 2007, while Giuliana married Bill Rancic the same year.
