He responded with a witty Instagram picture.

There's no denying James McVey and his fiancée, Kirstie Brittain are a pretty stunning couple. They're both slender, blonde, tall and have gorgeous glowy skin. Hmm... it's almost as if they resemble each other. Maybe just a little? Like cousins? Or... possibly like siblings? We really didn't want to be the ones to say it, but apparently, it's been a comment James has seen cropping up a lot. The 25-year-old musician and I'm a Celebrity contestant took to Instagram in a witty post that poked fun at such comments. The Vamps lead guitarist and vocalist posted a snap alongside his actual sibling captioned:

"Contrary to the world believing I am engaged to my sister, this is ACTUALLY my sister."

We were skitting at such a good response to the comments; James certainly has proved himself to be a good sport. James popped the question shortly after New Years to his long-term girlfriend, model and environmental student, Kirstie. He has stated that his time in the Australian jungle prompted him to decide to marry Kirstie and his I'm a Celeb BFF, Harry Redknapp was on hand to help with the ring selection once they returned to the UK. We can't wait to see the wedding pics already - no doubt they'll be sickeningly gorgeous!
