Kat Von D and Jeffree Star get into a major twitter row

There has to be something in the water right now, because social media feuds are poppin' off ALL over the place.

As if the whole Kim/Taylor and Chloe/Khloe dramz wasn't bad enough, now the beauty gurus of the world are getting antsy too. Seriously, we're finding it hard to keep up.

Yep, Kat Von D and Jeffree Star had it out on social media last night, and it all started when Kat shared a picture of Jeffree with a big 'no entry' sign across his face.
