Lookin’ good! When Alec Baldwin recently stepped out at Authors Night at a library in East Hampton on Aug. 11, fans couldn’t help but notice that the 60-year-old star appeared noticeably trimmer. And now, Star magazine has reported that Alec has shed 25 pounds and can credit his fit new physique to his wife, Hilaria Baldwin.

“She’s been on his case to lose more weight,” a source said (in the magazine’s latest issue, on newsstands now), adding that Hilaria, 34, has her husband following a vegan diet. “Alec loves that Hilaria keeps him young, but its hard for him to mantain such an intense diet and exercise regimen every day.”

“She’s being super-strict and not keeping any junk or sugar in the house, so if she’s not around, and he gets the chance to treat himself, he’ll take it,” the insider revealed. 

Hilaria previously opened up about her husband’s eating habits in her 2016 book, The Living Clearly Method, and said that Alec — who underwent hip replacement surgery this past February — first changed his diet once he learned that his blood sugars were at “pre-diabetic levels.”

“This was an alarming wake-up call that rocked him to the core,” she wrote. “This was a moment for drastically putting order where disorder had taken over; his body chemistry couldn’t re-balance until the aggravating foods and drinks were removed.”

As a yoga instructor, Hilaria knows that living clean isn’t only about eating healthy and regularly exercising. “I have found that being healthy is about not focusing on weight and rather on how I feel, how strong I am, and how healthy I am,” she shared on Instagram in June. “Weight and how you look are side-effects. Not the main focus. When I started focusing on health, my obsession with weight went away. They should not be confused.”
