Lady Gaga is well known for her bizarre behavior, but her latest alleged eccentricities are sure to shock even hardened fans.

Lady Gaga, 25, has been accused of leaving a London hotel room bathtub drenched in blood.

Rumors have flown around the net that Lady Gaga has started taking part in morbid Satanic rituals to keep her safe from spirits.

Staff at the Intercontinental Hotel in London were shocked when they went to clean Lady Gaga’s room and found blood in the bath.

However, the red substance has not been identified as blood.

One housekeeper claimed Lady Gaga was “bathing in blood as part of a Satanic ritual”.

The hotel maid 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.”

But other sources remain skeptical the “blood” was real and say it was more likely that the red liquid as part of a “weird” stage costume or prop.

An insider said: “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.”

It is unclear if Lady Gaga had actually bathed in the liquid last summer.

Lady Gaga is believed to be terrified of evil spirits and reportedly has every hotel and tour venue scanned by a team of paranormal investigators before she will agree to stay there.

The pop superstar, who is inspired by the spirit of her dead aunt, allegedly splashed out $45,000 on state of the art Electro Magnetic Field meters to detect spectres.

TMZ claim Lady Gaga has been named in a $380,000 lawsuit filed by a disgruntled former employee Jennifer O’Neil, who claims she is owed payment for 7,168 hours of overtime.

Jennifer O’Neil alleges that she was responsible for “ensuring the promptness of a towel following a shower and serving as a personal alarm clock” for the singer.

She also claims that Lady Gaga expected her to be at her service from the “earliest waking hour” and wanted her duties to extend to “stadiums, private jets, fine hotel suites, yachts, ferries, trains and tour buses”.

Jennifer O’Neil alleges that the schedule meant that she was unable to take breaks “or even at times sleep”.

A representative for Lady Gaga insisted to TMZ allegations were “completely without merit”.
