Home to face the music: Zayn Malik arrives back in London to be reunited with fiancee Perrie Edwards after quitting One Direction world tour following 'cheating' claims

Zayn Malik (left) looked sombre as he arrived back at London's Heathrow Airport in the early hours of Friday morning after being signed off the One Direction world tour with stress. It's expected the 22-year-old heartthrob will be reuniting with fiancée Perrie Edwards for the first time since a picture surfaced of him holding hands with tattooed blonde Lauren Richardson (inset) in Phuket, Thailand, earlier this week. Perrie, 21, (right) was seen leaving the couple's London home with a large overnight bag packed beside her at around the same time, and still appeared to be wearing her engagement ring. Zayn issued a public apology to the Little Mix singer on Wednesday evening after the pictures of him partying with Lauren at Seduction nightclub in Patong emerged online.
