Go on Netflix, turn on Grande's musical documentary Excuse Me, I Love You, and try to tell us that she wasn't spending half of that tour testing the Interstellar Highlighter Toppers (£22).
Available in 10 shades, Grande is admittedly in love with these silky, sink-right-into-skin formulas. "You can really use them anywhere — they're not just highlights," she said. "That's the thing about a lot of products in this line — they're multifunctional." Bonus: the compact kind of looks like a Motorola Razr from outer space, as Grande specifically demonstrated on our Zoom call: "Am I putting on makeup or am I calling Mars? To be determined."
