One Direction's Zayn Malik has been accused of cheating on his girlfriend Perrie Edwards with an Australian waitress.

Courtney Webb, also known as CJ, told British newspaper The Sun that the boyband hunk slept with her on Wednesday while Edwards was busy rehearsing for Little Mix's upcoming time on the road.

Webb, 21, insists Malik told her he was single before the alleged fling, revealing to the publication: "He's an absolute s**t. How dare he - not only to me but to Perrie?"

The waitress explained how the night's events unfolded - revealing she met Malik after going back to the superstar's £2.2 million home with a group of people following a night out in London.

According to the blonde, Malik insisted he was single before he allegedly bedded her.

The Daily Mail reports that: "But they soon fell asleep, which is when she took a photo of him and his recognizable tattoos lying in the bed."

Webb says she noticed a number of Edwards' belongings around the room, before confronting Malik afterwards.

He reportedly told her: "Don't worry about her she's on tour"

Edwards recently spoke out on her high-profile relationship with Malik, gushing: "Me and Zayn are really happy. We see each other quite a lot - the only time we don't is when he's in America. It's really hard but I trust him."
