Everyone has an opinion on Hugh Hefner's engagement to 24-year-old Crystal Harris. But what does Holly Madison think? She was Hef's girlfriend (well, one of them) for seven years.

In the season-two premiere of 'Holly's World' (Sun., 10:30PM ET on E!), a friend breaks the news (that she received over Twitter). "I feel like they just started dating," says her gal pal.

Holly used to think she'd get engaged to the Playboy founder. "I thought we were headed towards being exclusive -- marriage and family," Holly explains in voiceover during a photo montage of her with Hef. She ended the relationship when it was clear the 84-year-old wouldn't settle down with her. "I had a lot of different emotions and thoughts on [the news]. This was kind of a shock."
