The source also said: “He told a tale about how he tried to get Kylie to join him on stage at London’s Hammersmith Apollo and attempted to contact her.
“His emails bounced back, his WhatsApp messages were ignored and he couldn’t reach her on Instagram.
“Then he was in the audience at Hyde Park last month and Kylie’s manager asked him on stage at the last minute, so it wasn’t pre-planned.
“He said that’s why he didn’t sing during the track and talked about Kylie hogging the mic.
“The stories have started filtering back to Kylie through her friends — and her close circle don’t think she will be best pleased.
“It’s always disappointing to hear someone is making jokes at your expense.
“As far as Kylie is concerned, Jason is a great guy and she respects him, she’s just a busy lady.”
