Zayn Malik has left the One Direction world tour.
However, the band will continue to perform without him.
"Zayn has been signed off with stress and is flying back to the UK to recuperate," a rep told ABC News. "The band ]members] wish him well and will continue with their performances in Manila and Jakarta."
Malik, 22, has been plagued by reports that his relationship with his fiancée, Little Mix Perrie Edwards, is on the rocks. On Wednesday night, he tweeted that he loves her and slammed any rumors to the contrary.
"There's a lot of jealous f**** in this world," he added. "I'm sorry for what it looks like x."
The Associated Press also reported that authorities in the Philippines, where the band is scheduled to play as part of their "On the Road Again" tour, imposed a $5,000 "weed bond" on Malik and his bandmate, Louis Tomlinson.
The money will be forfeited if they use illegal drugs.
