Kesha has always had a unique sense of style, but she took it to a dangerous level at the BMI Pop Awards -- literally.

K Dollar Sign looked stunning in a black and gold flowy dress, gold headband and polished blonde curls (on the unshaved side of her head, that is). Her makeup was equally lovely, with dark eyeliner, shimmery shadow and a deep red lip. The 'Crazy Beautiful Life' singer looked straight, well, beautiful. But she got there in a risky way.

Kesha tweeted a photo of herself using eyeliner as lipstick, writing, "Puttin eyeliner on my lips. No big deal y'all." Thing is, it could be a big deal healthwise.

Us Weekly reports that the violet eyeliner Kesha used on her pucker instead of her peepers is pretty dangerous if ingested, according to the product's Material Safety Data Sheet. The liner, which appears to be CoverGirl's Liquiline Blast Liner in Violet Voltage, can make wearers sick if ingested -- and if you wear lipstick, you're bound to ingest some of it (women are estimated to ingest over five pounds per year!). The data says that "accidental ingestion of undiluted product may cause mild gastrointestinal irritation with nausea, vomiting and diarrhea." Ick!

Be careful, Kesha! That sounds worse than a Jack Daniels hangover.
