halloween hollywood bootsy bellows wig boob blood Matthew Mosshart kelly osbourne

Intentionally, of course!

Kelly Osbourne covered herself in fake blood to go dressed as horror queen Carrie to a Halloween party at Bootsy Bellows last night, and the Fashion Police host managed to make an otherwise scary outfit look glamorous!

The engaged starlet brought fiance Matthew Mosshart, who was dressed as a race car driver, as her date. Her man was actually the one who helped her achieve the festive look!

"Soooo excited for tonight's #Halloween costume!!! Getting my fiance to poor a bucket of blood over my head!!!" she tweeted.

Also at the fete was Kelly O's good pal Miley Cyrus, who came in the same Lil' Kim costume she wore the night before.

We wish it was Halloween every day of the year, because the celebs are so creative with their costumes!
