She is the hardest working - and hardest partying woman in pop music - and in just 24 hours , Rihanna pushed herself even further than she has before.
The singer swept into the UK yesterday aboard her private 777 tour plane, and within just 24 hours turned on the Christmas lights at Westfield's Stratford Shopping Centre.
Next she gyrated on stage in London's Kentish Town Forum at a private gig, and was up bright and early to head back to the plane at 6am. Phew!
Dressed in an animal print crop top, and matching shirt and trousers decorated with hands holding a cigarette, the provocative singer put on her best rude girl act, which included her now signature crotch-grabbing moves.
Celebrities including Stella McCartney, Chloe Moretz, Leigh-Anne Pinnock of Little Mix, turned out to see Rihanna bump and grind onstage as she performed her numerous hits.
However, before the real fun began, Rihanna's first appointment was a trip to the eastside of London to appear at an event which signalled the beginning of the festive spending season.
Waiving a fee she switched on the Christmas light's at London's Westfield Stratford City shopping centre on Monday evening.
Rihanna - who has been hit by over £200,000 in fines for repeated take off delays on her private Boeing jet - turned up an hour behind schedule for the ceremony.
And allegedly angered the 20,000 fans by performing just one song - the title track from new album Unapologetic
From there, it was off to Kentish Town where a flawless Rihanna barely broke a sweat as she performed for 2,500 fans as part of her 777 Tour.
London was the sixth stop on the gruelling tour, following stops in Mexico City, Toronto, Stockholm, Paris and Berlin.
Rihanna was in the area just a few months ago when she joined Coldplay to perform Princess of China at the Paralympics Closing Ceremony.
She was last called upon to flick a festive switch at the other Westfield on the other side of London in Shepherd's Bush two years ago.
It's all part of the ambitious promotional tour for her seventh album, Diamonds.
The singer has visited seven countries in as many days on a specially commissioned Boeing 777 plane and as well as her usual entourage the private jet carried a group of 150 fans as well as journalists.
But this plan, no doubt designed to generate favourable publicity has somewhat backfired on the star.
