Oops! Kylie Jenner's 2017 Calendar Got Her Birthday Wrong

How did this happen?!

Looks like Kylie Jenner's team has some more explaining to do...

The 19-year-old reality star came out with her own 2017 pinup calendar, but upon receiving the goods, fans quickly pointed out that the calendar gets one very important date wrong -- Kylie's own birthday. Kylie's birthday is on Aug. 10, but the calendar marks it as Aug. 20.

Oops.

This isn't the first time that Kylie's had issues with her various projects. On Tuesday, Kylie tweeted that she wasn't going to post personally on her app anymore, after she said a "very personal post" about spicing up her sex life with boyfriend Tyga and spoiling him by cooking for his friends went live.

"A post went up today quoting something that I NEVER EVER said or saw," Kylie tweeted. "A very personal post that I would never ever approve. And it's unfair to me and you to think that those were my words. I'm sorry and I know we will figure something out so we can all be satisfied."
