But for all her outrageous outfits and hairstyles – she likes to wear skin-tight PVC and shape her hair into a large bow - the young American keeps her make-up surprisingly demure.
Bourjois makeup artist Cassie Lomas has been working with Lady GaGa since she came to the UK and explained the concept behind her look: "Exactly because of her striking clothes and hairstyle, Lady GaGa likes to keep her makeup nude so there's some balance to her look, and works a classic 60s vibe with pale colours that almost blend into the skin.
"That's why I start with a clean, matte base, such as Brush Foundation, £11.73, contouring the cheeks with a bronzer that defines her bone structure without adding too much colour – try Delice De Poudre Bronzer, £6.84.
"Lady GaGa likes to make an impact with her eyes, but still downplaying the colour, so I use neutral smoky browns on the lids from Eyeshadow Trio in Le Naturels, £6.35, with a layer of heavy, liquid black eyeliner and finishing with Volume Glamour Ultra Curl Mascara, £7.82 – it lifts and curls the lashes without an eyelash curler so they blend in perfectly with the false eyelashes I add on top to really make the eyes stand out.
"Finally, she really likes her lips to blend into her skin colour with a true nude lipstick – Sweet Kiss with its satin finish in Beige Elegant is spot on."
