It's hard to believe that the world's favourite royal couple would be best pleased if they saw The Daily Telegraph's original front page last night.

Previews of the newspaper's front page began to circulate on Twitter late last night and it featured a unfortunate blunder.

A picture of William, Kate and Prince George was placed underneath the unrelated headline, 'Toddlers at risk from extremists,' and it sent the internet into a frenzy.

While the blunder has since been fixed, the mistake has been doing the rounds on various social media platforms thanks to some quick to act tweeters. 

The Telegraph updated its first edition. But I wonder which will be delivered to Kensington Palace this morning? pic.twitter.com/0qg9INzn7L
