It is seriously gorgeous.

When a new season arrives, many of Hollywood's most famous faces opt to switch things up with their hair. Whether it's going for the chop; going much, much longer or switching up their colour, it feels like there's always a new 'do on show. The latest celebrity switching things up is Lady Gaga, who recently appears to have totally changed her hair colour. Except for her role in A Star Is Born, the singer-and-actress has kept her hair a shade of platinum blonde for...well, just about as long as we can remember. Now, the 32-year-old has debuted a big change - and in a very low-key way. Her fiancé, Cristian Carino, posted a photo of her to his Instagram account earlier this week and eagle-eyed fans couldn't help but notice the big change. While he new hair 'do still has a little bit of her signature platinum hue, there is no doubt about it: her lilac locks are stunning.  It's not totally clear if the dye is permanent, or if it is a temporary colouring. As her hair is already bleached blonde, the pastel hue could be added to her hair with real colour pretty easily. Then again, there are plenty of options out there for spray colours or temporary colours - perfect for people who like to experiment with their look - which would appear equally as vivid in blonde hair. Either way, though, we love it.
