However, on Monday, as the couple arrived at Ballina airport in New South Wales, Anna’s bare ring finger couldn’t be missed.
It still remains unclear whether the couple are set to walk down the aisle.
Tim, comfortable sharing information about the issue, confirmed to KIIS FM’s Kyle and Jackie O show in November that he knows Anna’s taste if he was to propose.
‘It’s three years on, so probably getting around that time,’ Tim revealed. ‘I know where I’d probably go to get [the ring]…I know what she likes. I need to steal one of her other ones to find out the size.’
