Christina Aguilera Manages to Remain Calm After Embarassing 'Fluid' Incident [Photos & Video]

Christina Aguilera's stars seem to be going haywire at the moment, as the "Dirty" singer keeps on suffering from mishaps one way or another.

After going through a series of unfortunate events, which includes messing up the lyrics of the national anthem at a game and splitting her lip after a painful fall at the Grammies, the 31-year-old popstar had an unfortunate wardrobe malfunction while paying tribute to the legendary Etta James at her memorial service.

While performing "At Last," one of James' classic, photos and videos captured a reddish-brown fluid trickling down Aguilera's legs. The media has also captured the "Voice" judge bending down, trying to wipe off the liquid with her sleeve.

Many speculations were made about the "mysterious fluid," including a theory of it being menstrual blood. Later a source told US Weekly that the liquid was just spray tan that had come off because of the heat.

However, the Grammy-winning artist continued with her performance without showing the least hesitation.

"One of the greatest moments of my life ... Singing with my idol, the legendary Etta James. You will be forever missed," she tweeted after the show.

The following day, on Jan. 31, Aguilera was spotted attending a show (Immortal World tour by the Cirque du Soleil production), celebrating the late "King of Pop" Michael Jackson's life, with boyfriend Matt Rutler and son Max.
