But when Goodrem was asked for her response to the bizarre rumours this week, she remained tight-lipped.

According toThe Daily Telegraph, when she was asked if there was any truth to the speculation at a press conference, she stressed "she was not going to discuss it".

"Even when the journalist suggested that they personally did not believe the gossip, Goodrem was not swayed to join the conversation," the outlet reported.
