The singer and Joshua Sasse announced their engagement in February (16) after a whirlwind romance, and both were forced to deny they had wed last month (May16) after a report claimed they had tied the knot in Greece on Kylie's 48th birthday.

Joshua laughed off the report, and wrote on Twitter, "Apparently I was at a big fat Greek wedding... wish I'd been there! @kylieminogue," adding the hashtag, "#rumoursrumoursrumours".

Kylie confirmed there had been no wedding by reposting her fiance's message on her own official page.

But the speculation began again when 28-year-old actor Joshua posted a poem entitled 'To My Wife' by William Ernest Henley on Instagram on Saturday (11Jun16).

It reads, “Take, dear, my little sheaf of songs, For, old or new, All that is good in them belongs Only to you; And, singing as when all was young, They will recall Those others, lived but left unsung - The best of all.”

Joshua later posted an image of D.H. Lawrence's Women in Love book cover, with one fan commenting, "There's a whole lot of love on your Insta (sic). Hmmm..."

The stars have been dating since meeting and falling in love on the set of Joshua's medieval comedy Galavant last September (15), and announced their engagement in the marriage section of Britain's Daily Telegraph newspaper.

"The engagement is announced between Joshua, son of the late Dominic Sasse and of Mary Heale (nee MACauley), of Herefordshire and Kylie, eldest daughter of Ronald and Carol Minogue, of Melbourne, Australia," read the notice.

Reports suggest Sasse proposed during a skiing vacation in Switzerland over the Christmas holidays.

Kylie was previously engaged to Spanish model Andres Velencoso, but the couple split in 2013. She also dated Halle Berry's ex-husband Olivier Martinez and tragic INXS star Michael Hutchence.
