Meanwhile, Zayn Malik's younger sister, Waliyha, is stunned by the death of Liam - who had seven-year-old son Bear with former girlfriend Cheryl Tweedy - and was lost for words.

She wrote on Instagram: "Literally heartbroken. RIP. I have no words."

Harry Styles' mother, Ann Twist, also paid tribute to Liam.

She shared a broken-hearted emoji and wrote on Instagram: "Just a boy ..."
