Lady Gaga fan kills cat for concert outfit

A desperate Lady Gaga fan has been charged with animal cruelty for allegedly killing her cat and using the dead pet's blood to complete an outfit she planned to wear to one of her heroine's concerts.

Angelina Barnes, 20, had smeared her face and arms in the cat's blood and was just about to leave her Oklahoma City home for a Gaga concert earlier this week when a relative walked in on her - and saw the carnage.

Local news station KFOR-TV reports the cat had been cut to pieces after Barnes drowned the pet in the bathroom.

The animal's liver was found in a make-up case.

Barnes was taken to Griffin Memorial Hospital in Oklahoma, where she is receiving treatment after being diagnosed with depression.

Lady Gaga famously performed at the 2009 MTV Video Music Awards covered in fake blood.
