And whilst Kylie has come a long way since finding fame on Aussie soap Neighbours, she proved that she’s not forgotten her roots by reuniting with her former co-star and ex Jason Donovan at the bash – awww.

The former couple posed for a sweet picture together and were also joined by fellow Neighbours alumni turned Hollywood star Guy Pearce. We do love a good reunion!

Kylie was certainly looking glam for the occasion and donned a floor-length gold gown whilst sporting her hair in loose waves.

Ever the performer, she joined Scissor Sisters frontman Jake Shears for a spot of karaoke and it was seriously cute.

HAPPY BIRTHDAY KYLIE!!!! Realized last night, we met almost exactly 15 years ago. Life flies by, and you can’t make old friends. Love you.❤️👨🏻‍🌾👸🏼❤️

The songstress clearly had a ball – and also took the opportunity to seemingly confirm her new romance with GQ creative director Paul Solomons.

Kylie posted a cosy snap of the pair cuddling up on Instagram and wrote: ‘Birthday girl’

Meanwhile Paul shared the same picture – nawww.

It comes after Kylie split from fiancé Joshua Sasse last year.

As well as throwing a starry party, Kylie has marked turning the big 5-0 by posting a series of nostalgic photos.

The star ended her trip down memory lane by sharing a newer snap of herself cheekily holding a guitar in front of her scantily-clad bod and revealed how excited she is about what’s to come.

‘And so a new decade begins. How thankful I am for the opportunities life has afforded me. 50….. Let’s go!’ Kylie told her Instagram followers.
