The 26-year-old is the new face of the beauty-tools brand, and has been drafted in to bring some serious star power to the launch of their new Gold series of hair stylers.
And since the range features three different new stylers, we get three different Katys - shot beautifully by famed photographer David LaChapelle.
The first ad, shows the new Mrs Russell Brand going all romantic on us in a frothy sheer frock and vintage 'do, while the second has her reincarnated as a boho princess, reclining on a chaise longue with long glossy waves and thigh-high boots.
'I'm so excited to be working with ghd, especially using their tools on my California Dreams Tour to get me stage ready,' says Katy. 'ghd products have a reputation of being the best products in the biz, and I like being associated with that.'
'I'm very excited to reveal the styles I did with legendary David LaChapelle in the upcoming ghd campaign'
