It comes after Megan slammed recent Love Island stars for ‘ruining the show’.
Having appeared on the show herself in 2018, Megan claimed that contestants are now more interested in brand deals than shaking things up on the series.
The star told The Sun that people are ‘too safe’ and concerned about how they come across since influencer Molly-Mae Hague’s success in 2019, wanting to emulate her popularity.
Megan said: ‘I did watch Love Island this year. Everyone is being too safe. They want to sit on the fence and not offend anyone or steal anyone’s boyfriend.
‘I think that because people like Molly-Mae have gone on to make billions of pounds, people are being too sensible because they want to be liked.’
The television personality also claimed that in previous seasons of the show, people would be ‘ruthless’ and let their personalities shine through.
Now, she believes the show also needs fresh perspectives and a new format.
The beauty has suggested that there should be a version for middle-aged people or an LGBTQ+ series.
Megan quipped that the series is in need of ‘Karens’ who have deep conversations and know what they want instead of people who just want a PLT deal.
