Pop star Kylie Minogue has reportedly split from her fiancé, the British actor Joshua Sasse.

The singer, 48, met Sasse, 29, in 2015 on the set of US series Galavant, in which he stars and she was making a guest appearance.

The pair announced their engagement just five months later in February 2016 in an announcement in the Telegraph. But, according to The Sun, the Australian star has now called it off because she suspects Sasse of cheating on her with Spanish actress, Marta Milans.

A source told the paper Minogue is devastated by the split and “no longer trusts him”, reportedly asking him to move out of their West London home.

It comes days after a pre-recorded interview Minogue did with ITV’s This Morning aired, showing her gushing about Sasse and talking about their wedding.

She also recently told You magazine that she planned to take her husband-to-be's name when they married.

She said: "Kylie Sasse is a great name... Kylie Minogue has never exactly tripped off the tongue. I'll definitely be taking Sasse but there will be Minogue in there somewhere."

Back in December, she also opened up about the couple’s battle to have children as she admitted it is a “different kettle of fish” as you get older.

The couple were thought to have been planning to wed in Melbourne, although had made it clear they would not do so Australia legalised gay marriage.

It would have been the first wedding for both of them, although Sasse has a son from a previous relationship.

Minogue’s previous long-term partners include Spanish model Andrés Velencoso, fellow Neighbours actor Jason Donovan and French actor Olivier Martinez.

There was no comment from representatives for either Minogue or Sasse. Milans - who filmed US drama No Tomorrow alongside Sasse in Canada last year - has also not commented on the reports.

Earlier on Thursday, Minogue tweeted that she had signed a new record deal with label BMG.

She wrote: "#lovers ... So happy to announce my new record label is BMG. I promise you will have my heart..." Sasse has not tweeted since December 20.
