article: Over the past couple of weeks it hasn't just been Zayn Malik's departure from One Direction that has been making the headlines, it's been his personal life too. For Zayn's relationship with Little Mix singer Perrie Edwards as come under scrutiny as the 22-year-old was once again accused of cheating on his fiance. At the weekend Swedish model Martina Olsson claimed that she had slept with Zayn while he was holidaying in Thailand recently. Scroll down for video . Zayn and Perrie pictured in happier times, the young couple have this week jetted off on what was thought to be a make or break holiday following accusations of him cheating . The 24-year-old told The Sun On Sunday's James Beale: 'Perrie should not stay with Zayn any longer because he has cheated on her and continues to lie about it. It is not the first time either, so maybe she will walk away.' And Martina is right, this isn't the first time Zayn has been accused of cheating. In fact, the pair's union could be compared to that of Cheryl Fernandez-Versini and Ashley Cole. The similarities are certainly there. Like Cheryl and Ashley both Zayn and Perrie, 21, have enjoyed a huge amount of fame. And like Cheryl and Ashley their romance has been dogged with cheating allegations, almost from the start. Cheryl and Ashley were happily married until she discovered that he had cheated on her on several occasions . The X Factor alumni twosome first got together in August 2011 but by August 2012 it was being reported that Zayn had been filmed through the keyhole of a hotel room with another woman. Then in February 2013 the couple were hit by a kiss and tell when Australian waitress Courtney Webb told The Sun newspaper than she had bedded the then 20-year-old. Courtney - who took photos of Zayn while he was asleep - said at the time: 'He's an absolute s**t. How dare he - not only to me but to Perrie?' She also added: 'I definitely don't think it's the first time he's done this. I feel sorry for Perrie - she doesn't know this is going on. It's wrong and it has to stop.' Then at the beginning of March Zayn was pictured with his arm around a girl named Lauren Richardson in Thailand, a second shot showed the pair holding hands. Zayn has been accused of cheating on four occasions, the first was by Courtney Webb (left), the most recent was Swedish model Martina Olsson . When Courtney claimed she had bedded Zayn she claimed took these photographs of him apparently sleeping in her bed . After this picture of Zayn with Lauren Richardson was released he Tweeted saying that he loved Perrie . This photograph enraged One Direction fans as it appears that Zayn is holding Lauren's hand in the picture . That was, in fact, the only time that Zayn, who left One Direction last week after five years in the band, has made any comment on the stories of his betrayal. He took to Twitter to say: 'I'm 22 years old... I love a girl named Perrie Edwards. And there's a lot of jealous f*** in this world I'm sorry for what it looks like x' But just a week or so later Martina's claims came out. She alleged that Zayn had asked her to share a shower with him before taking her to the bedroom of the apartment where he was staying. For Cheryl, who is now re-married, the cheating rumours eventually became too much and she ended her marriage to Ashley in 2010. At the time the footballer had been accused of cheating her two years. The first was hairdresser Aimee Walton who claimed to have slept with him. By February 2010, just a month before Cheryl announced their split, four more women had come forward to say the same. Zayn and Perrie got engaged in 2013 but he has since been accused of cheating on her on several occasions . Tracey Cox says that Zayn's level of fame will be difficult for someone so young . But Perrie, who accepted Zayn's marriage proposal in August 2013,  is currently sticking by her man - who has yet to comment on the latest allegations. She and Zayn were pictured boarding a private jet earlier this week and are thought to be on a 'make or break' holiday. For the most part though, despite the on-going accusations of infidelity, Zayn has remained relatively high in public favour - unlike Ashley. We spoke to relationship expert Tracey Cox who told us that this could be because he is younger. She said: 'I think at this point the public are more lenient on him because he is a young guy in a boy band rather than a footballer, who are known for excessive behaviour and thinking the rules don't apply to them. 'But the main difference between his behaviour and that of Ashley Cole is that he's young. 'His fame might seem appealing but the reality of coping with that much money and fame at such a young age is going to have consequences. 'Of course, he's going to make some mistakes along the way. I believe him when he says he's stressed. Will Perrie and Zayn's relationship ended up like Cheryl and Ashley's? Tracey continued: 'Ashley is older and, as an adult, should have the maturity to go beyond instant gratification to be able to think through the consequences. 'The other difference of course is that Ashley was married to Cheryl while Zayn is dating. There's a different level of commitment there. 'But, even having said all that, I would join others in cautioning Perrie about trusting him again. 'The evidence appears clear that some type of infidelity is happening on a regular basis and by taking him back after each incident, Perrie is effectively saying it's OK to cheat.' MailOnline has contacted Zayn's representative for comment.
