Although Malik's mother claims her son is "fine", according to reports in the Mirror, the news comes days after two rumours circulated about Malik's personal life and possible substance abuse. 

Malik was accused of cheating on his fiancée, Little Mix's Perrie Edwards, after photographs of him with his arms wrapped around another woman and holding another's hand were shared on social media. Malik took to Twitter on Wednesday (18th March) to deny the rumours. '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," Malik wrote. 

Another report suggests Malik and his band mate Louis Tomlinson may have run into some legal trouble in the Philippines. The two are reportedly required to pay a 'weed bond'. The $5,000 bond will be forfeit if either Malik or Tomlinson are caught using drugs whilst in Manila this weekend. The Bureau of Immigration, according to Yahoo, are concerned because of a video posted online which purportedly shows Malik and Tomlinson using and discussing drugs.
