Demi Moore is the latest star to cite "exhaustion" for her recent trip to the hospital, and she's far from the first Hollywood A-lister to suffer from the ailment.
Life in the public eye must be so tiring, as countless others have used the same excuse for heading to the ER or rehab, and RadarOnline.com takes a look back at some of the high-profile victims of extreme tiredness.
As RadarOnline.com previously reported, 49-year-old Ghost star was rushed to a hospital in Sherman Oaks, California on Monday night and is now seeking professional help "to treat her exhaustion and improve her overall health," according to her publicist, Carrie Gordon.
Lindsay Lohan's career hit the rocks while filming I Know Who Killed Me in 2007, and after missing repeated days of work she checked herself into the Wonderland Treatment Facility. Instead of admitting her late night partying being to blame for skipping work, the actress said she was extremely exhausted, and "going through a really bad time then."
Disney star and Justin Bieber's main squeeze, Selena Gomez, was rushed to the hospital after collapsing from a mysterious illness last June, in what was said to be a sickening combination of exhaustion and food poisoning.
Exhaustion struck Rihanna while she was touring in Sweden, causing the Umbrella singer to cancel her Stockholm show after she was hospitalized with flu-like symptoms.
Despite her high-profile drink and drug problems, even Rehab singer Amy Winehouse blamed exhaustion for cancelling tour dates in 2007. The now deceased star later confessed that she was hospitalized after overdosing on a mix of substances, including heroin, ecstasy, cocaine, ketamine and alcohol.

Lady Gaga seems super human, but even she wasn't immune to the affects of exhaustion when she collapsed before a planned performance at Purdue University in West Lafayette, Indiana in January 2010. The Poker Face singer apologized to her Little Monsters for letting them down, tweeting: "Paramedics came to take care of me, and told me my heart-rate was irregular -- a result of exhaustion and dehydration."
Whitney Houston proved she was a bad flier during a diva breakdown midair last October, when she exploded on a flight attendant and almost got thrown off the plane. "She was not drunk or on drugs, she is in the middle of filming a movie and flew across country to attend a charity event and return to filming. She was exhausted," a source told E! about the incident.
