Ke$ha's gravity-defying, towering 'do looked like a cross between Marge Simpson and Jedward. Backcombed into a huge mohawk, we dread to think how much hairspray this took to hold in place.
Meanwhile, it was another day, another 'do for Rihanna who had her signature scarlet locks transformed into a mass of spiral curls. This is our favourite Rihanna look to date.
Kelly Osbourne had also opted for big and bouncy. She looked like an extra from Dynasty with her shoulder-legth blonde hair blow-dried to into a huge bouffant.
We give Rihanna the thumbs up for her bouncing curls. Which star do you think had the best hairstyle. Leave a comment below and tell us your thoughts.
