There are 13 different shades to choose from, and all have fun feline shade names, Catoure, Cosmo Kitty and Pink Paws.
This year at Coachella music festival Katy seized the opportunity to promote her new Katy Kat Matte lipstick range.
She headed to Instagram to showcase a few of the new colours in the collection.
In the pictures Katy hash-tagged each different lipstick modelled by her and her friends.
“I was always experimenting with makeup,” Katy tells Vogue.
“What’s so interesting is that even though I grew up in a sheltered household, even though I wasn’t allowed to wear thongs or anything like that, my mum would say, ‘You should put on a little lipstick’—from age 12! It was very strange, but I was wearing lipstick of all colors from 12 and 13. I’d use it on my cheeks, my eyes, and I was very into classic reds.
“When I started developing my own sense of style, I thought I was a pinup girl. I was obsessed with them at 13: I’d do a black liner and a red lipstick and that was my go-to.”
Katy says Tumblr is where she gets all her inspiration from.
“I follow really cool people that are just being themselves, and then I start to follow their friends. I’m a bit of a voyeur because no one really knows I’m watching their lives.
“Tumblr to me is a safe place because it’s more about the art than the conversations – it’s not about likes, so it’s not a narcissistic social platform.
“There are reblogs and stuff like that, but it doesn’t have that same feeling of double tapping. I like that it’s a more pure place that is more creative.”
Katy says she prefers a matte finish to a gloss.
“I want to put my lipstick on once in the early morning and not have to think about it for quite a few hours, you know?
“My lipsticks are a moisturising demi-matte because sometimes mattes can make you look like you haven’t drank water in two weeks.
“Obviously you don’t want scabby lips just because you want your lipstick to stay forever! You want to look hydrated.”
The new collection will launch in July, 2016.
