The reality star is known for her love of fitness and healthy eating but that didn’t stop some of her Instagram followers from suspecting foul play.
“I posted a photo to my Instagram last week during a shoot I was doing. Now I know I shouldn’t read comments on websites but I can’t help myself sometimes,” she said.
"I also got some direct mails on Instagram telling me I didn’t need to Photoshop myself, so I thought I would use this opportunity to set the record straight,” she wrote in her Sunday World Column.
The Dublin model insisted that the photo was completely natural and admitted she has no idea how to use Photoshop.
“I didn’t Photoshop myself in this picture at all, I used filters, but I don’t even know if it’s possible to Photoshop a picture so small. And I don’t know how to use Photoshop either.”
Vogue pointed out that her thigh gap did look different than normal but explained it was probably due to the angle she was standing at.
The 29-year-old has been living the high life since splitting from ex Brian McFadden and recently shared pics of her new bachelorette pad in London.
