Theyโre both musical legends in their own right and now romance rumours have gone into overdrive after the pair were spotted walking hand-in-hand through the empty streets of London following Kylieโs gig at the British Summer Time festival in Londonโs Hyde Park on Sunday.
The talented duo enjoyed a romantic midnight stroll and didnโt hold back on the PDA.
Photographs of Chris, 38, and Kylie, 47, published in British newspaper The Sun show the pair linking arms as they strolled past Parliament and Buckingham Palace before moving onto St Jamesโs Park.
According to an onlooker, the singers looked seriously smitten.
โThey were in their own little world, they seemed oblivious to anyone around them,โ a witness told The Sun.
Despite the rainy British weather, the stars werenโt deterred and continued on their secretive stroll.
Earlier in the day, the Spinning Around hitmaker had performed to over 60, 000 punters at a popular music festival.
โIt was a beautiful Summer Solstice night. Thank you to youโฆbeautiful audience,โ Miss Minogue wrote on social media following her energetic set.

Just hours before her moonlight stroll with Chris, Kylie delivered an energetic set at the British Summer Time festival in Londonโs Hyde Park on Sunday
Chris had spent time with his two children Apple, 11 and Moses, 9, at Piccadilly in central London for Fatherโs Day celebrations before meeting up with the pint-sized pop princess.
Chris, who most recently dated American actress Jennifer Lawrence, and Kylie have been longtime friends.
Last September the Melbourne-born beauty even made a cameo at one of Coldplayโs gigs in Sydney with the pair performing Kylieโs hits Where the Wild Roses Grow and Canโt Get You Out of My Head.
โWe asked her [to perform with us]! You have to submit a request five years in advance and then you go through an extensive interview processโฆ And then you have to have a medical screening, then you get washed down with disinfectant and then you might be able to do it,'โ Chris joked at the time to 2Day FMโs Dan and Maz of securing the star for the surprise collaboration.

Chris still remains close to his former wife, actress Gwyneth Paltrow
Despite splitting from his wife Gwyneth Paltrow in March 2014, Chris is still on good terms with the actress.
Meanwhile, in the past Kylie has admitted that sheโs ever hopeful when it comes to finding The One.
โI donโt think I am unlucky in love I just think itโs hard to find the right person,โ Kylie, who has dated model Andrรฉs Velencoso, actor Olivier Martinez and singer Michael Hutchence, has mused.

Chris most recently was linked to Jennifer Lawrence
