NEW YORK (Web Desk) - As the fashion mogul, 42, continues to rapidly lose weight over the past few years, friends are expressing their concern for her well-being, wondering if she s using healthy methods to drop the pounds.

"She continues to lose more and more weight, and it s alarming," an insider close to the blonde beauty told Radar, adding pals are "extremely worried about her."

Fans also expressed how concerned they were about Simpson s size as she s proudly flaunted her small physique on social media, often showing off how she can fit into her young children s clothing.

"At 42, with three children, what woman fits into clothes she wore as a child? Someone [needs to] step in and help her," one social media user penned beneath a snap of the "With You" singer in her eighth grade cheerleading jacket.
