Gwen Stefani losing sleep over Blake Shelton's THIS habit

Blake Shelton's fluctuating weight has become a major concern for his partner, Gwen Stefani. 

An insider revealed to Life & Style that Shelton's weight has been yo-yoing, with the singer struggling to maintain a healthy lifestyle.

"Everyone agrees something needs to change for the sake of his health," the source emphasized. Shelton's weight has reportedly soared to 250 pounds, prompting concerns from those close to him.

"He admits he needs to lose at least 20 pounds," the insider continued. However, Shelton's love for indulgent foods, such as barbecue pork sandwiches with all the fixings, hinder his efforts.

"He can't seem to stick to a healthy diet no matter how hard he tries," the source noted. "He's going hog wild on his favorite foods."

Stefani has jokingly threatened to send Shelton to a "fat farm" if he fails to curb his overeating habits. The couple's friends and family are worried about Shelton's health and well-being.
