Lady gaga gets highlighter happy highlights

We haven't seen much of Lady Gaga recently, and when we have she's been looking disappointingly normal. All that changed today though, as Gaga stepped out for the David Letterman show with highlighter-yellow highlights. Never one to shy away from colour, here we see her working with a fairly neutral, some-might-say-normal blonde base. That's where the normal ends though, thankfully. Splashes of neon yellow throughout make this look just that bit more eye-catching - and way more Gaga. Can you even imagine the inside of Lady Gaga's wig wardrobe?
