Lady Gaga gets in on the lilac beauty trend, but is it super cool or a step too far?
We think it looks pretty cool against her bleach blonde hair locks, but the unusual tie-dye effect isn't one we'll be trying at home.
But Gaga isn't the only celeb who loves getting handy with the felt-tip pens...
Peaches Geldof had a 'mad' moment when she moved to New York and dyed the tips of her hair bubblegum blue.
We reckon it was inspired by Luella's Spring/Summer 08 catwalk models, who walked down the runway with bright blue fringed - trust Peaches to be bang on trend!
Avril Lavigne loves a touch of pink in her hair to give her that girly, rock chick look.
Do the celebs look cooler with a wacky flash of colour, or does it just not suit their image? Have you ever dyed your hair a mad colour? Comments please!
