RiRi, 26, opted for a loose-fitting white shirt, black leggings and boots for the basketball game on 9 May.
A baseball cap kept her sleek long locks in order, and she'd slicked on a deep red lipstick to add a touch of trademark Rihanna glamour.
So simple, we thought!
But then we had a closer look.
As Rihanna stood up, she flashed her bare midriff in a teeny tiny crop top hidden under her baggy white shirt.
She'd also added at least a zillion rings on to her fingers, themselves perfectly manicured in a blood red colour, obvs.
Her trainer-style boots actually had enormous heels on them, and her 'simple' leggings were decorated with stars.
Ah, there we go! Rihanna's not gone all casual on us after all.
The superstar was joined by her bestie Melissa Forde for the game, and the girls sipped drinks as they watched the Clippers take on Oklahoma City Thunder in Los Angeles.*
*Soz for the sport bants.
When she's not sitting court-side, Rihanna's been busy working on her eighth album and partying it up at the Met Gala.
