Lady Gaga is a vamp
But this one was for Valentine's Day with her boyfriend, actor Taylor Kinney.
She also bought fangs and fake blood for The Vampire Diaries star to wear.
A source said: "Gaga wanted to treat Taylor given that this is their first Valentine's Day together.
"She ordered it online about three weeks before the big day because he loves vampire-style sex sessions.
"They had a very laid-back evening at Taylor's house drinking lots of red wine and eating spaghetti."
She also gave him a copy of her music video You And I with added footage of them both.
Edited video and a naughty outfit? Sure beats watching Dirty Dancing and eating a box of orange Matchmakers.
