The former Destiny's Child star was close to looking stunning from top-to-toe at the star-studded bash.
Close... but not quite. If only that sugary pink lipstick had been filed in the bin, circa 1984!
Michelle joined a whole host of celebrities who walked the red carpet at the Nokia Centre in Los Angeles, including Mariah Carey, Tatyana Ali, Janelle Monae and Amber Rose.
Her stunning dress was a real winner and Michelle's hair looked shiny and gorgeous, dressed in soft waves and parted to one side.
But we have to mark her down for that awful choice of lippy.
Pale, chalky pink is never a good look. And especially not with Michelle's gorgeous complexion. Tut and indeed, tut.
Next time Michelle, stick with what you're good at – wearing dark nudes or deep, berry reds.
And if you do fancy something new, stay away from the pasty pastels and go bright with a fuchsia pink, hot orange or cherry red shade like these gorgeous Diego Dalla Palma Lipsticks, £15, marksandspencer.com which look great on darker skin tones.
Come on, it's not rocket science!
