There’s no argument that Lady Gaga takes the cake when it comes to strange behavior, but she may have found a way to take it even further. A staff member at the lavish Intercontinental Hotel in London is claiming that the singer left a large amount of blood in her suite’s bathtub last summer. Although the pool of red liquid was never confirmed as being blood, the housekeeper claimed that Gaga was “bathing in blood as part of a Satanic ritual,” reports UK newspaper The Independent. The employee also claims that when she reported it to the concierge, she was told to “put it out of her mind.” Others are guessing the so-called blood is just part of another one of Gaga’s eccentric costumes or stage acts, much like in her performance of Paparazzi and Poker Face at the 2009 MTV Video Music Awards. This wouldn’t be the first time Lady Gaga has caused a stir while on tour. She’s been known to bring people in to investigate her potential accommodation for any signs of paranormal activity. There has been no word yet from Mother Monster or her reps regarding the claims.
