John Legend had 'heart of a 50-year-old'
The singer's recent health kick annoyed wife Chrissy Teigen.
R&B singer John Legend overhauled his diet after his doctor warned him he had the "heart of a 50-year-old".
The All of Me star, 37, reveals he had been carrying a few extra pounds for some time, but his waistline took a real hit when his supermodel wife, Chrissy Teigen, started testing out recipes for her new cook book.
"I was gaining weight for a long time," he explained during a joint appearance with Chrissy on U.S. talk show Kocktails With Khloe. "I started gaining weight when she was starting her cook book and I had been like, a few pounds overweight for quite a while."
However, John didn't really change his lifestyle until he received a real wake up call following a routine doctor's visit.
"Then I went to my doctor, and they said I had the heart of a 50-year-old!" he laughed. "And so I decided to start watching my cholesterol, and now I'm losing weight."
The interview with Khloe Kardashian, which aired in the U.S. on Wednesday night (20Apr16), was taped weeks before Chrissy and John became first-time parents last Saturday (16Apr16), and the then-heavily pregnant beauty admitted she was annoyed by his health and fitness kick - because she was eating for two.
"(He) is working out twice a day now," she jokingly moaned. "He's on the strictest diet, eating so clean!"
John has likely started to relax his strict regime after becoming a dad, as the couple settles in to life as new parents.
Chrissy gave fans a sneak peek at their daughter Luna Simone in a sweet snap on Instagram on Tuesday (19Apr16), and on Wednesday (20Apr16), John delighted fans by sharing a new photo, showing off little Luna's full face.
