Rumours intensified on Monday when an Australian magazine hit newsstands detailing Kyle's new "relationship" with Tegan.
An anonymous source told the magazine: "Kyle has fallen for his personal assistant, Tegan. Everyone in Kyle's inner circle, including Imogen, has known about the relationship for a while, and given that Kyle and Imogen haven't lived together for most of the past year, I'm surprised the news hasn't come out before this."
Another insider told the magazine: "It's become increasingly serious. Kyle endorsed Tegan's brother's wine company, Nueva Sangria, to help out the family in June, and when Kyle was with Tegan in LA in September, they were clearly a couple. It's no secret to anyone in the inner circle."
Meanwhile, another source told The Daily Telegraph the rumours are true: "Everyone knows [Kyle and Tegan] are together... For Kyle, it is all about her, he doesn't spend time with anyone else other than her. It is common knowledge in [his] inner circle."
A source claims the reason for their split was largely due to Kyle’s reluctance to make a commitment.
“Imogen has desperately wanted to get married and have kids for quite some time now but unfortunately Kyle wasn’t ready,” a source told New Idea.
