American singer Lady Gaga is always in the news, it seems, and usually for rather weird reasons.

This time around, the word is she apparently left large amounts of blood in the bath of London's lavish Intercontinental Hotel, after staying there last summer.

The hotel staff, when cleaning the 25-year-old singer's room, was shocked upon discovering the pool of red liquid and was, for some time, left perplexed as to what it actually was.

One of the housekeepers claimed Gaga was bathing in blood as part of a Satanic ritual.

While she is known for her belief in paranormal activities, could she actually have been doing so?

Meanwhile, there are others who believe Gaga must have used the pool of red liquid for the purpose of some weird stage costume or prop.

Although it is unclear whether the liquid was indeed blood, this is not the first time the singer has been in the news for weird and unusual behavior at hotels.

Gaga, for instance, is known to ask for the hotel to be scanned by a team of paranormal investigators before she agrees to stay there.

She believes in paranormal activity and won't take any risks when she is on the road. It's important to her to be safe from spirits, a source was quoted as saying by showbizspy.com
