Eighty-three pounder Nicole Richie has told all of her socialite squad that she is indeed pregnant. According to celebrity tattles, BF Joel Madden insisted “The Simple Life” reality show star go into rehab after he got the news.

“If she didn’t get healthy for the baby’s sake,” say a Star Magazine source, “he’d dump her!”

With that ultimatum in mind, the twenty-five year old checked herself into a Corona Del Mar, California area rehab facility for outpatient treatment on May 11.
