The singer pulled out of the stint in Hong Kong yesterday (March 19) so he could fly back to the UK to be with his family.
A spokesperson for the band said: “Zayn has been signed off with stress and is flying back to the UK to recuperate. The band wish him well and will continue with their performances in Manila and Jakarta.”
It comes after he took to Twitter to blast pictures which emerged of him with a mystery girl in Thailand this week (March 18).

Now younger sister Waliyha Malik, 16, has taken to Instagram to write: “Don’t worry guys, Zayn is going to be okay very soon. All the stress has just gotten to him because of the rumours and hatred he has heard and received. It’s really hurting him, some people are just giving him to much.”
She continued: “People need to realize my brother is human to, stop hating him because he hasn’t done anything to anybody, except for defending himself because of what people heard of what he did, but it isn’t true. I love my brother to death, and I do not want to lose him for anything, it hurts me to see him not feeling good.”
“Please pray for my brother, please help him because I know he will be okay. please stop sending him hate and getting on him for what he has ‘did’.”
Malik is currently dating Little Mix singer Perrie Edwards. He has responded to the claims, writing:
I'm 22 years old… I love a girl named Perrie Edwards. And there's a lot of jealous fucks in this world I'm sorry for what it looks like x

Despite missing the band’s last three shows in Manila and Jarkarta, Malik is reportedly expected to return for the first of two shows in South Africa on March 28.
Earlier this week, it emerged Malik and Tomlinson had also been ordered to pay a $5,000 (£3,300) drug bond ahead the band’s shows this weekend.
They would lose the bond if they were caught using or promoting the use of illegal drugs during their visit to the country, according to the Philippines Bureau of Immigration.
