Poor Crystal Harris.

Through tears, a newly single Harris confides to ET, that although she is “relieved,” she feels her biggest regret in breaking the engagement was that she “disappointed everybody.”

“It happened so fast,” she says of her decision to marry Hefner, admitting that the glamorous whirlwind of fame played a large part in what may have been a hasty decision.

“Hef asked me to marry him in front of three cameras and a photographer. I thought it was something I wanted.”

She can push out as many tears as she wants… just don’t push out any more music. That crap is just awful!
