Aside from jumping around our living room to her no1 hit 'We Found Love', we spent the evening with serious outfit envy.
The Bajan star always picks the hottest outfits - but the tartan puffball skirt she rocked on the ITV1 show's stage was one of our faves.
Ri paired the Scottish-style mini-dress with a white pointed collar shirt (bang on trend), black tights and fierce F-word shoes.
We liked her frock SO much, we've scoured the virtual high street and found it.
The Alexander McQueen item isn't cheap - £465 at Selfridges or Net a Porter - but we reckon if we saved up ALL our money for it we might well wear it every single day until Christmas.
Just think of all the combos - knitted jumper over it for a laid-back look, killer heels for the Xmas party.
Alternatively if you haven't got a cool £500 in your bank account, here are some other tartan pieces we lurve this season...
