In a radio interview this morning, shock jock Kyle asked about the speculated romance, saying: 'How long has it been?'
Justin responded, 'I'd say a few weeks, Kyle.'
Kyle then probed the reality star on whether his new girlfriend, Ashley, was nicer to him than she was to her MAFS partner Troy Delmege, to which Justin responded: 'Yes, a hundred percent!'
The news comes as the couple have been spotted several times together in the last several weeks, including on dinner dates and romantic strolls around Sydney.
Listen to Justin's interview below.
