Shut up and party: Wild Rihanna risks burning out again as she misses flight and cancels work after boozy night out
09:22 GMT, 20 May 2012
She was hospitalised for 'exhaustion' earlier this month following a stint of partying mixed with her hectic work schedule.
Now Rihanna is sparking fresh fears she could be spiralling out of control again as she has been spotted out partying once more.
And she let her hair down so much she even missed her flight out of London this morning and managed to bag another day off to recuperate.
The Disturbia singer jetted into the city yesterday, following an evening of letting her hair down in Hollywood, to attend a party held by Jay-Z and Kanye West.
Out partying: Rihanna is sparking concerns she's set to burn herself out again as she was spotted partying in London with Jay-Z, Kanye West and Kim Kardashian
Helping hand: She clutched on to her girl friend as she left London's Dstrkt venue after letting her hair down
And she was seen in high spirits as she giggled and clutched on to her friend as she left the Dstrkt venue.
Rihanna, 24, had been in the club with the likes of Kanye West and Jay-Z, who had completed one of their Watch the Throne concerts to hold a 40th birthday party for manager Tyran Smith.
And she mingled with Kanye's girlfriend Kim Kardashian, who was also inside, while her brother Rob Kardashian and his girlfriend Rita Ora were also on hand to party the night away.
Jay-Z's pals Gwyneth Paltrow and her husband Chris Martin also showed up, while Stella McCartney also completed the A-list guest list.
Ouch! Rihanna even grabbed hold of her friend's hair as she was led through the crowds
Holding hands: Her night out in London came just a couple of nights after she was seen dancing the night away at the Roxbury nightclub in Hollywood
Rihanna went for a more sophisticated number in the wardrobe department compared to her recent outings as she stepped out in an all black ensemble.
She wore black trousers with a jacket, while her hair was worn sleek.
And she finished her look off with lashings of red lipstick.
Watching her step: Rihanna looked in a giggly mood, just two weeks after she was hospitalised for 'exhaustion'
But she lost her demure stance as she clutched on to her girl friend while leaving the party.
A giggly Rihanna even grabbed her pal's hair to guide her through the crowds, while she was also seen holding her hand and shoulder as she left.
And she'd clearly had a lot to drink as she woke up still drunk this morning with lapses in memory of her night out.
She wrote on Twitter this morning: 'U know life is great when u wake up at 9 am DRUNK!!!!! #London #happybirthdayTYTY #G4L #H0Navy.
Star turn out: Rihanna mingled with the likes of Kim and Kanye inside as they celebrated manager Tyran Smith's 40th birthday
'You know it was a good night when u wake up n run to your BFF's room like… How did I get in my bed Did I walk Stumble Get carried'
And she even managed to miss her flight, before Jay-Z managed to give her another day off as she wriggled out of her latest work commitments.
She added: 'So ummm…. I'm supposed to be on a plane rt now! #r
'JayZ saved me!!!!! I got an extra day off sorry @HiHatprod.'
It comes just two nights after she was seen dancing the night away at Hollywood's Roxbury nightclub with a bottle of champagne in her hands.
Star bash: Rita Ora and Gwyneth Paltrow were also on hand to party the night away
And only two weeks ago she was rushed to hospital after partying at the Met Gala in New York.
The You Da One hitmaker tweeted a picture of herself attached to an IV drip in a hospital, while MediaTakeOut alleged she was suffering from 'exhaustion and dehydration'.
Support: Paltrow was joined by husband Chris Martin at the party as they mingled with their pal Jay-Z and Kanye West's girlfriend Kim Kardashian
However, after a brief stay in the undisclosed medical centre, she was discharged and allowed to fly back to her home in Los Angeles.
But it sparked fears she had been burning the candles at both ends by working hard in the studio, promoting her movie Battleship across the globe and partying in between.
