In a statement to ET on Thursday, the British boy band's publicist said that 22-year-old Zayn Malik "has been signed off with stress" and is flying back to the UK to recuperate. The rest of the band's members -- Louis Tomlinson, Harry Styles, Liam Payne and Niall Horan -- will continue with their upcoming performances in the Philippines and Indonesia without him.
"Zayn has been signed off with stress and is flying back to the UK to recuperate," the statement reads. "The band wish him well and will continue with their performances in Manila and Jakarta."
Zayn has been in the headlines recently for some not so good reasons, including reports that he cheated on his fiancé, Little Mix member Perrie Edwards. However, he quickly took to Twitter on Wednesday to directly address those claims.
"I'm 22 years old... I love a girl named Perrie Edwards. And there's a lot of jealous f**ks in this world I'm sorry for what it looks like x," he wrote about the controversial pictures that feature him showing PDA with another woman.

Last month, the singer also left a One Direction show in Perth, Australia early after falling ill. As 1D fans had pointed out on Twitter, this wasn't the first time Zayn battled health issues. This past November, he was so sick that he didn't take the stage in Orlando, Fla.
In November, Matt Lauer drew the ire of plenty of 1D fans when he asked about rumors surrounding Zayn and "substance abuse" on the Today show, when he missed the band's promotional appearance for their latest album Four. At the time, Liam insisted that Zayn had a "stomach bug."
Not surprisingly, Zayn wasn't pleased about the question.
"I'm really angry and upset by what was said on the Today show," the 21-year-old singer told The Sun in November. "I was really ill at the weekend, that's why I couldn't fly to America."
That wasn't the first time the band has been questioned about alleged drug use.
Last May, Zayn and Louis Tomlinson were caught on camera in a video obtained by the Daily Mail lighting up what looks to be a joint, while joking about drugs. Liam apologized for his bandmates on Twitter later that month, writing, "I love my boys and maybe things have gone a little sideways I apologise for that. We are only in our 20's we all do stupid things at this age. We all have a lot of growing up to do in an extreme circumstance I'm not making excuse but it's fact we are gunna fall short somewhere."
