Kentish Town Forum oozed excitement last night (19 November) as teen fans and fashion greats united to see popdom's most precocious star strut her stuff on the London leg of her much-touted 777 tour.
Over in the VIP box, Stella McCartney rubbed shoulders with Pixie Lott, Chloe Grace Moretz and showbiz veteran Kylie Minogue. It says something when someone with three decades in the business turns out to see you.
Even the accessories within the 2,500-strong crowd were suitably bling and eye-catching, in homage to the night's big name: stud detail and leopard print vied for attention next to killer heels and vampish belts.
Rihanna herself was late and loud: just as fans in the HTC-sponsored gig were starting to get a bit restless and the beer flowed just a bit too easily, she stormed on-stage - shades and post box red lippie to the fore.
It's hard to know where previous rumours of Rihanna being exhausted came from: for someone who's spent the past six days jumping between planes and hotel rooms, her energy levels were impressive, alarming even.
Belting out a string of hits including Umbrella, Diamonds and Only Girl, she pouted, shimmied and rocked it in the way only Rihanna can.
Gyrating around the stage in a leopard print conical bra (what else?), she combined verve with powerhouse vocals in the hour-long show - to celebrate the release of her seventh album, Unapologetic - and her enthusiasm was infectious.
"You guys are definitely something exciting because I think me and all of my 777 crew have been waiting to get here," she yelled to the (adoring) crowd.
Even the bit where she stopped midday through Where Have You Been to complain to the engineers about the backing track was all part of her trademark theatrics (or, as she put it - the "b******* of a rock 'n' roll tour").
With pace and energy and sheer sex appeal at full throttle, the Rihanna effect was in full flow.
At the end of an epic night, Ri-Ri wrapped up with a storming performance of We Found Love and left the crowd yelling for more.
"Need to catch me some shut eye.. Gym in the morning. Night beautiful beasties xxx" she later tweeted. At last she sleeps...
