Lady Gaga

Lady Gaga has been seemingly everywhere lately -- on the road with her Monster Ball Tour, meeting the Queen of England, shooting an episode of Oprah Winfrey's show that airs later today -- and the pop star's demanding schedule may have taken a toll on her health. The singer was scheduled to play at Indiana's Purdue University last night, but canceled the show at literally the last minute. After openers Semi Precious Weapons and Jason DeRulo performed at the college's Elliott Hall of Music, the crowd was informed "Lady Gaga will not be able to take the stage this evening due to sudden illness."

"Due to exhaustion and dehydration, Lady Gaga collapsed and passed out before her show tonight in West Lafayette, Indiana," the singer's publicist tells Rolling Stone. "Her physician has advised her to take a few days off to rest." Lady Gaga's rep didn't specify how long she'll be out of commission; the Purdue show has been rescheduled for January 26th.

Lady Gaga plays four very in demand shows at Radio City Music Hall starting Wednesday, 1/20.
