Kylie Minogue's sparkler fuels engagement rumours

Kylie Minogue has sparked rumours she may be engaged to boyfriend Joshua Sasse after being spotted wearing a large diamond ring.

Kylie Minogue has been spotted wearing a huge diamond ring, fuelling engagement rumours.

The Australian singer was seen wearing the dazzling square- shaped diamond on her left ring finger while attending the NME music awards on Wednesday.

Minogue, 47, further fuelled speculation this week, when she was photographed by paparazzi concealing her left hand while walking in London.

Not usually camera shy, the singer walked with her left hand in her jacket pocket.

Minogue confirmed her romance with British actor Joshua Sasse in November last year.

According to British newspaper The Sun, Sasse, 19 years Minogue's junior, popped the question during the Christmas holiday period.

Neither Minogue or Sasse's management have confirmed the engagement. In a recent interview with You magazine, Minogue gushed over life with Sasse.

"I can't actually put into words how happy I am. We just completely fit together. He gets me, I get him," she said.

The pair met when Minogue appeared as a guest star on Sasse's show Galavant, in September 2015.
