Speaking to Metro, the music mogul's spokesman Max Clifford insisted that the couple have not lost touch and remain in a relationship.
"They'll be together again this week. She is flying over," he said. "Although they have been apart, they have been speaking every day on the phone."
However, Clifford did little to refute suggestions that Cowell and Hussainy are holding back their wedding until next year.
"I've never actually heard Simon talk about a wedding. Whenever he is asked he says, 'Who knows?'"
