At the J.W. Anderson for Topshop afterparty last night, Nicola showed off her brand new hair shade - dip-dyed pink! The star grinned from ear-to-ear at the bash which was held at London's saucy Madame JoJo's club. What do you think of Nic's fashion-tips?
Take a look back through some of her recent hair 'dos (and some of her hair don'ts) before you decide...
Last November Nic experimented with some heated rollers to create this old-school glam 'do for the InStyle party, where she told us she even did her own make up. This is definitely one of our fave Roberts looks
As a natural redhead Nicola has long experimented with shades close to her original shade. This uber-vibrant red 'do form 2010 looked glossy and we loved the soft curls but the shade was just a bit too harsh for the pretty singer's pale complexion
There was way too much hair styling product going on here. Nic's poor locks look laden down!
Another of our faves, this curled up 'do looked fun, pretty and cool. Nicola soft strawberry blonde colour worked well alongside her creamy skin
Nice try, Nic, but you're not distracting anyone from your tattas with that giant sideswept fringe
Possibly not one of her best moments, Nic tried out pastry-style granny chic last year
In 2008 Nic went back to her red roots and dyed her newly-lopped bob a rich auburn shade which left her locks looking glossy and healthy
We've been pondering over this long blonded look for a while. Is it a wig? It certainly looks like Nicola was getting wiggy with it back in 2007
In the very early days Nicola used to dislike her ginger locks so much she'd cover them with super-dark brown colour. A pity, we say, because we love her fab fiery locks!
