The 'Diamonds' singer kept herself busy by attending the Roc Nation Brunch in LA, before making her way to the Clive Davis and Recording Academy Gala (after a quick outfit change, of course!)
Keen to show off some leg, RiRi rocked a red and white skirt with a huge thigh-slit for brunch, adding a striped shirt which she left completely unbuttoned.
She wore her raven tresses in natural curls, finishing her look with nude lipgloss and a stand-out pair of white criss-cross heels.
But later that day the songstress upped the ante by flashing even more flesh in a floor-trailing silky yellow gown by Alexandre Vauthier.
Flaunting her pins with an even bigger thigh-slit, the Barbadian beauty looked glowing as she teetered along in a striking pair of gold strappy heels.
Her eye-catching frock also featured a plunging neckline which looked highly prone to a wardrobe malfunction - let's hope she packed some tit tape in case of emergency!
She kept her locks the same but added a pair of silver hoop earrings and a dazzling statement necklace.
To finish? Pillar-box red lippy, of course!
