Los Angeles, Feb 13 (EFE).- Lady Gaga has been forced to postpone four concerts in her Born This Way Ball tour because of acute joint pain arising from an injury, the singer said on her Web site. The 26-year-old artist is suffering from synovitis, an inflammation of the joints. "I am completely devastated and heartsick. I've been hiding this injury and pain from my staff for a month, praying it would heal, but after last night's performance I could not walk," Lady Gaga said in a statement.

In Los Angeles -- the land of paparazzi, dazzling dental work and endless glitz -- it turns out that you, too, can be hot enough to draw a crowd. For a price, of course. Crowds on Demand is the brainchild of a young entrepreneur who came up with a novel idea for giving everyday people a taste of fame, even if it is brief and bogus. The Oscars are coming up on Sunday, but you don't need to win an Academy Award to have a following. But why would anyone fork over several thousand dollars for artificial adulation?
