With a phenomenally hectic schedule and little downtime to rest, Rihanna needs her beauty sleep more than most.
So it must have been a particularly painful inconvenience when she was rudely awakened at 6am this morning.
The 24-year-old was evacuated from her London hotel in the early hours after a lift shaft suddenly caught fire.
She found herself outside along with 300 guests who were disturbed as fire engines arrived on the scene to deal with the accident.
The star tweeted a picture of a fire engine outside the hotel in Whitehall Place to her 21.5 million followers.
She wrote: 'Roamin da streets since 6am! Fyah in da telly #evacuationlife'.
The singer also posted a photo of herself slumped in the back of a taxi wearing a hoodie and sunglasses.
A London Fire Brigade spokesman said no one was injured in the blaze.
Meanwhile a spokesman for the hotel said the fire caused a small amount of damage to a lift on the 7th floor of the building.
Around 10 firefighters dealt with the incident after being called at 6.22am.
The singer closed the Hackney Weekend festival on Sunday night with a performance that included a string of her hits and a surprise (albeit widely expected) guest appearance by her mentor Jay-Z.
The singer took to the stage as the sun was setting over East London's Hackney Marshes to the tune of her 2010 hit Only Girl In The World.
She followed her first track with Disturbia and S&M, which saw her jump off the stage and greet the audience.
After her third song, Rihanna informed the crowd that her mic pack was slipping, and enlisted the help of a thrilled fan in the front row to re-attach it to her bra strap.
Rihanna-brawl club shut by New York officials
NEW YORK -- New York State is shutting down the trendy SoHo nightclub where Drake and Chris Brown had a bloody throw-down over Rihanna.
The State Liquor Authority (SLA), which filed 14 charges last Friday against W.i.P. and the Greenhouse club where it is located, voted Tuesday to suspend the club's license to serve booze.
The emergency suspension followed a string of violent incidents reported to the SLA by the NYPD, documenting seven assaults and fights beginning March 11 and leading up to the big brawl June 14.
The SLA's charges also involve drug activity inside the club, lack of supervision, becoming a drain on police resources and using the name "W.i.P." without the authorization of the SLA.
"The SLA will not tolerate violent bars that break the law," SLA Chairman Dennis Rosen said. "This should serve as a message that this agency will not hesitate to take immediate action when licensees pose a threat to public health and safety."
The club is entitled to an expedited hearing on the license suspension before an administrative law judge.
The bloody bottle brawl started when Drake allegedly sent Brown a note, taunting the hip-hop star, "I am f*ck*ng the love of your life," referring to Rihanna.
The hip-hop stars and their entourages fought with fists and bottles, injuring at least eight people, including San Antonio Spurs star Tony Parker, whose cornea was scratched.
Parker filed a $20 million lawsuit against the club's owners, charging that they should have known better than to let the dangerous duo hang out in close proximity.
A rep for W.i.P. declined to comment.
