Kylie Minogue has split from her fiance

Popstar Kylie Minogue has reportedly split from her fiancé Joshua Sasse over rumours he'd been having an affair.

Minogue, 48, called off the engagement over suspicions the 29-year-old British actor had been getting close with Spanish actress Marta Milans, a source told The Sun.

Sasse and Milans worked together on TV drama No Tomorrow in 2016.

The source said Minogue, who was "absolutely devastated", had asked Sasse to move out of her home.

The pair announced their engagement in February 2016 after meeting on the set of US TV show Galavant in 2015.

Australian Minogue recently told YOU magazine she planned to take Sasse's surname when they married, saying "Kylie Sasse is a great name".

"Kylie Minogue has never exactly tripped off the tongue."

Spokespeople for Minogue and Sasse refused to comment to The Sun.
