Yasmine always had that round face / soft body that indicated the fat bomb was ticking. Bridget was skinny with a thin face and features. That is what makes her so shocking.
Yasmine was also coked up most of the 90's and probably early 2000s. She had to get nasal reconstructive surgery because she went through so much coke it burned holes in her nostrils.
That aided her in keeping weight gain at bay for a long time.
Hypothyroidism? My mom had/has it and it really sucks. She is in better shape now at age 76 than in her 40s and 50s as they had not gotten her medication right.
