It may be a new year, but Lady GaGa is still up to her old tricks - this time apparently leaving a bathtub filled with blood at a hotel in London.

The Marry The Night singer, who is known for her eccentric behaviour, has now been accused by staff at the plush Intercontinental Hotel of "bathing in blood as part of a Satanic ritual" after a housekeeper found the tub of red stuff in GaGa's suite.

The stunned hotel worker told website Truthquake: "Lady GaGa left large amounts of blood in the suite during a stay this summer. The incident was reported to the concierge, who was told to put it out of her mind."

Speaking of the gory discovery, a source told The Sun: "All of the hotel's staff are convinced she was bathing in it or, at the very least, using it as part of one of her new costumes or weird stage routines."

The 25-year old has previously used fake blood for a performance of Paparazzi and Poker Face at the 2009 MTV VMAs.
