Kylie Jenner's risqué calendar has a massive mistake inside

Kylie Jenner kick starts the new year by releasing a 2017 calendar, so you can have her on your wall all year around - if you want to that is.

The American TV personality released the calendar, photographed by the controversial Terry Richardson.

However, eagle-eyed superfans fans quickly noticed a crucial mistake in the calendar

There's a little note from Jenner, on 20 August. '20 today!'... Except, that's not her birthday.

Jenner's birthday is the 10 August, 1997. Not 20 August.

People on Twitter didn't pull their punches...

According toTMZ, the first batch of calendars, which were being sold exclusively on Jenner’s online shop, hard Dash Dolls, all have the mistake.

Who knows? These first editions might fetch a pretty penny on Ebay.

Someone is probably in a lot of trouble right about now.
