BLAKE BLOWS UP AGAIN

Gwen gives up on slimming down scale-smashing singer

- 

BLUBBERY Blake Shelton’s belly is bigger than ever — according to sources, who say the country heavyweight’s fit wife, Gwen Stefani, is finally throwing in the towel after years of trying to help him control his junk food addiction.

“She’s done being his watchdog. She loves him, but she feels like there’s nothing she can do — and she’s sick of nagging him,” an insider says.

Alarming new photos show the God’s Country crooner, 49, has a much wider waistline, and diet expert Dr. Stuart Fischer, who has not treated Blake, estimates the 6-foot-5 star is crushing the scales at nearly 300 pounds.
