And here's Perez's (way more interesting) take on the issue:
Us Weekly has learned exclusively that Nicole Richie, 24, and fiance Adam ‘’D.J. AM'’ Goldstein, 32, have called it quits. ‘’They have decided to break off the engagement,'’ Richie’s rep Cindy Guagenti confirms to Us. ‘’The decision is mutual.'’
"Adam was fed up with Nicole," said one source. "Her issues with her weight, I'm reluctant to say 'anorexia', caused her behavior to be very erratic and moody lately."
Another source said that...Adam found out that Nicole was 'partying' when he was away, and he does not tolerate that."
....Surely he's not mad at her for getting suddenly skinny? Granted, she used less orthodox methods to achieve it than him (cocaine vs. surgery?) but still, talk about the (ex-fat) pot calling the (ex-chubby) kettle black (skinny)!
