Adorable 'Two Broke Girls' actress Kat Dennings had a bit of a bloody accident and had to go to the emergency room after cutting open her hand in her home.

She captioned the first photo of some bloody paper towels yesterday (Jan. 5) with "Relaxing Sunday #stitches #emergencyroom," and the following two with an emoticon of a screaming cat and a thumbs down.

Based on information we gleaned from her Twitter, it sounds like Kat sliced her finger open while washing some knives in her home.

As she wrote:

We assume she's referring to kitchen knives, but if you want to imagine that in her spare time she's a ninja assassin, we're sure that would be totally cool with her.

You can check out the photos of the aftermath below. There will be blood.
