A source says he is seeking further medical treatment from the “no. 1 cardiologist in the world,” via People.

“He’s still working through his health issues. He was supposed to appear on Fallon but isn’t able to due to doctor’s recommendations,” they added.

Zayn confirmed the hospitalization on Friday (April 18), posting from a hospital bed.

“To my fans – Thank you to all of you for your love & support now & always- been a long week and am still unexpectedly recovering,” Zayn wrote over a photo of himself laying in a hospital bed.

“Heartbroken that I can’t see you all this week, I wouldn’t be in the place I am today without you guys and am so thankful for your understanding.”

Afterward, it was confirmed that he canceled meet and greets at the Looney Tunes Record Store on Long Island, Newbury Comics in Boston, Rough Trade in New York City, and the Sound Garden in Baltimore.

He’s supposed to go on his first solo headline arena tour later this year. We wish Zayn a speedy recovery!
