Kylie Jenner is suffering from food poisoning.

She said: "I went to the doctor again because I had food poisoning over the weekend and it has not been fun. "So that's why I've been a little MIA or if my Snapchats aren't as fun and exciting as they usually are."

But the 19-year-old television personality has now assured fans that she is "back in action" and went to have her eyebrows and nails done.

In a video posted to her Snapchat account, she shared: "But I'm back in action. I just got my nails done today earlier. I'm about to get my eyebrows done ... Ugh, I don't look sexy right now at all."

Meanwhile, Kylie's stepsister Khloe Kardashian previously revealed details about Kylie's diet.

She shared: "Kylie eats like a typical teenager but she's also super aware of what she puts in her body when it comes to fresh and organic foods. It's all about that moderation, too!"

And Kylie is busy working on expanding her Kylie Cosmetics range and wants to eventually release foundations, blushers, concealers and bronzers.

She wrote: "I can’t believe I’m 19!!! When I look back at the past year and all that has happened, it’s seriously crazy. I can’t even imagine what this next year will bring – not only for me, but for my friends and family too! Check out some of my hopes and dreams for my 19th year!
