The Aussie pop star was catching the Eurostar to Paris to mark turning 46 – yep, we can't quite believe she is 46 either!
And Kylie was dressed perfectly for the occasion, opting for a cream statement coat, which featured a monochrome pattern trimming.
The Into The Blue singer kept the rest of her outfit simple with a pair of staple black skinnies and black top. Kylie also upped the glam factor with a pair of a-mazing black stiletto heeled boots – jealous!
Despite the rain, Kylie still decided to wear her black rounded shades – well, she is a celeb after all. And she toted around her essentials in a lust-worthy black bag!
As for make-up, Kylie kept it simple with flawless skin, and from what we can see, there's not a single imperfection or wrinkle in sight – what is her secret?!
She painted her nails a pretty pale pink for an elegant finish, and wore her hair pulled away from her face – another way to show off that perfect complexion!
Paris is clearly a fave of the glam star's, as she was also there at the beginning of the month. We can definitely think of worse places to spend your birthday!
The former The Voice judge has been swamped with hundreds of birthday wishes from fans and took to Twitter to thank them, saying: "I'm so overwhelmed by all the lovely birthday wishes…Thank you so much."
Happy birthday, Kylie! If we look half as good as you at 46, we'll be made up!
