Dua Lipa’s been tearing up the stage on her “Radical Optimism” tour … but even pop queens need a breather, and she grabbed hers before lighting up Miami!

Check it out — Dua flaunted her insanely toned, bronzed bod in a teeny metallic bikini at The Setai Miami Beach on Thursday, even tugging the strings down while lounging to dodge those dreaded tan lines.

Dua kept it makeup-free and low-key — scrolling her phone, chatting with a pal, and soaking up chill vibes as she recharged.
