It seems the pressure of being an international pop star is taking a toll on One Direction singer Zayn Malik. The 20-year-old Brit appears to have recently dropped a significant amount of weight from his already-slim frame, and an insider tells Us Weekly it's likely due to the stress of his busy schedule.
"He's lost a lot of weight," the source says. "He started to eat healthy a while ago and working out to get in shape as he had never trained before. He wanted some definition."
(Indeed, Malik recently tweeted about enjoying a nutritious snack. "Think I'm gonna have some weetabix with a banana now," he wrote on June 2.)
"He's always been the slimmest of the band members, naturally," the insider adds, "but I think he's running around a lot, getting stressed, and not putting health first."
"Running around a lot" is an understatement. The British-born teen idol — along with bandmates Harry Styles, Liam Payne, Niall Horan, and Louis Tomlinson — has been working nonstop on One Direction's 2013 U.S. Take Me Home tour, which kicked off Thursday, June 13, at Fort Lauderdale's BB&T Center.
In the next three months alone, the group is expected to perform more than 35 shows in cities all over the U.S. They're also busy doing video shoots and promotional appearances for their new movie, This Is Us, due later this summer.
