Dannii Minogue looks effortlessly chic as she enjoys a night out in London after celebrating major milestone

Dannii Minogue cut a chic figure in London as she posed up a storm after celebrating a major milestone for her clothing label.

The Aussie pop star, 52, was a vision in black as she posed on a London street at dusk on Tuesday.

Dannii flaunted her sartorial style in a black crew neck top that she wore under a matching-coloured blazer.

The Put The Needle On It hitmaker also rocked a pair of loose-fitted black trousers to finish her effortlessly chic ensemble.

Leaving her locks free to cascade down her shoulders, Dannii augmented her outfit with a pair of strappy stilettos.

She also added a hint of colour to the ensemble with s stylish black handbag featuring a gold chain embellishment.

Dannii's retinue of followers were quick to fawn over the fashionable photos.

'The Queen is in town,' one fan gushed.

Another said they were jealous that they don't enjoy similar street vistas when looking out their window.  

'Just imagine looking out your window on a random street in London and seeing Dannii Minogue doing a little photo shoot for her insta,' they wrote.

'All I see out window is cats fighting and the odd drunk person stumbling home from the pub.'

Dannii  recently celebrated 10 years of her clothing label Petites after jetting off on a holiday with her boyfriend Adrian Newman and son Ethan.

The Australian singer marked the milestone by sharing footage to Instagram of the label's first runway show Down Under.

'It is an absolute joy to celebrate 10 years of my label Petites for @targetaus,' Dannii wrote on Wednesday.

'I got to create not only the label, but Australia's first ever Petite mannequins and Australia's first Petite runway show.'

The singer went on to thank everyone who backed her to create the range in a time when shorter women had no other option except to have their clothing tailored.

'Since then petite models are a new and emerging division at model agencies. To Target, and all my team who have worked on Petites over these years, thank you.'

The old clips show Dannii smiling, laughing and modelling looks for her fashion line created for Target.

Petite clothing is specifically designed for women whose frames are 5'4' and has been cut proportionally to fit and flatter a petite frame.

The milestone comes after Dannii was recently spotted jetting off on a holiday with her rarely-seen son Ethan and her boyfriend Adrian Newman.

The Love and Kisses singer had her hands full with luggage as she made her way to check in after arriving at Sydney Airport.

Dannii welcomed her son, now 14, with former rugby league player Kris Smith back in 2010.

The pair dated 2008 to 2012 after meeting in Ibiza in 2008 while he was celebrating his 30th birthday.

Ethan has remained largely out of the spotlight throughout his childhood and Dannii previously said her son didn't know she was a pop star.

Dannii and Adrian also famously keep their romance under wraps and rarely speak about each other publicly.

Earlier this year, Dannii gave a rare insight into their low-key romance and opened up on the prospect of marriage.

Of keeping their relationship out of the limelight, she told Hello: 'I haven't always been able to do it that way before because if the other person is already famous, then what can you do? But he works behind the scenes, so it's easy.'

'Marriage isn't on the cards, but we're just enjoying growing up together and spending time,' she added.
