The actress wore a purple one-piece swimsuit with Monday emblazoned across the front while treating herself to a spa day at The Retreat Hotel, where rooms cost upwards of $2,300 (AUD) a night.

'I had the most relaxing time here,' she captioned a video.

'...The lagoon is heated by geothermal steam and is this gorgeous blue [colour] because of the algae and silica in it. It’s really therapeutic for you and your skin.
