The Kardashians: Beauty Company Sues ... You Can't Break Up Over Makeup

The Kardashians need to seal their beesting lips, and if they won't a judge will seal them for the girls ... at least that's the goal in a new lawsuit against the brood.

Haven Beauty is outraged the klan has publicly bashed them. As we first reported, the Kardashians claim the company has falsely represented that Kim, Kourtney and Khloe are behind the makeup line.

Haven insists, in new legal docs, the girls are just trying to weasel out of the deal they made, so they're asking a judge for 2 things.

First ... an order prohibiting them from talking smack against the company.
