Zayn Malik allegedly cheated on fiancée Perrie Edwards with a blonde Swedish beauty twice before quitting One Direction this week.
Martina Olsson, 24, claims she spent the night with the former 1D star, 22, behind the back of his Little Mix fiancée while he on tour with his band in Thailand earlier this month.
The girl says she met Zayn – who quit 1D this week saying he wanted a “normal” life after flying back to the UK due to “stress” - on a night out and went back to the boys’ villa before doing the same after clubbing again 48 hours later.
She told The Sun on Sunday: “He didn’t mention anything to me about having a fiancée. He was really flirtatious and I fancied him a lot.
“When he was taking me to bed in a gorgeous hotel suite overlooking the ocean, he didn’t seem too stressed. I thought he was a really nice person but he was obviously under pressure from somewhere.
“He quit because he can’t keep up his carefree, party lifestyle while in a relationship.”
Martina met the One Direction lads after she was picked from the crowd to join them in the VIP area of Seduction nightclub in Patong, Phuket by the band’s security guard Alberto Alvarez.
She claims she met Zayn’s bandmates Louis Tomlinson and Liam Payne in the club and had some drinks with about 12 other people before she was invited back to the boys’ house.
It was back at the group’s accommodation that Martina first set eyes on Zayn. She said: “I saw him walk from his room and said to my friend, ‘Who’s that? He is so good looking.’”
She was told he was in the band too and the pair soon got talking after he asked her if he could get her something to wear in the pool.
She said: “Zayn was flirting with me. He was on the sun lounger and said, ‘You have a really nice bum and look so good.’”
At 9am Martina claims Zayn asked her to join him in the shower where they allegedly kissed before heading to bed.
Martina left the villa that morning but spotted Zayn in the same nightclub 48 hours later where he was with Lauren Richardson, the girl he was pictured with shortly before leaving the One Direction tour to fly back to the UK due to “stress”.
The singer invited Martina back to the villa again but she felt awkward as she thought he’d been flirting with Lauren.
She said: “I was jealous as I really fancied Zayn. I was thinking, ‘I was with him first!’ I told him she looked old and he laughed.”
But, despite Lauren seemingly grabbing the star’s attention earlier, it was Martina he allegedly took back to his bedroom in the early hours of the morning.
Martina later uploaded a picture of herself partying with Zayn to Instagram but it was soon spotted by One Direction fans.
She emailed the band’s security guard Alberto to ask for advice as she was left shaken when Directioners started asking questions and she decided not to respond to any of them after speaking to him.
Hours later Zayn had quit the band’s tour and tweeted: “I’m 22 years old... I love a girl named Perrie Edwards. And there’s a lot of jealous f**ks in this world.”
Martina concluded: “Zayn is a spoilt child who likes female attention. He will probably insist that I’m lying when it’s he who refuses to tell the truth."
This is not the first time the singer has been accused of cheating – a picture emerged of him in bed at his London home with Australian Courtney Webb two years ago.
However, Zayn and fiancée Perrie put on a united front this week and were pictured looking at houses for sale on the day his departure from One Direction was announced.
Breaking his silence after leaving the band, Zayn praised Perrie for her support, describing her as “a good girl – very supportive”.
