"I wonder if she could say the same of him?" Bishop told the Australian Broadcasting Corporation, when asked whether she would be flattered or offended if the comment were directed at her. "I'd be taken aback, I think. It's a rather interesting comment to make," she said.
Bishop declined further comment on the Paris remark, but added an unprompted observation on Trump's use of social media, saying she wouldn't "run a commentary on his Twitter account".
A bad start
The criticism follows an acrimonious January telephone call between Trump and Australian Prime Minister Malcolm Turnbull, when the American hung up after 25 minutes rather than the scheduled hour, according to the Washington Post.
In June, the relationship between the two countries hit the spotlight again, after the release of a leaked tape of Turnbull mocking Trump at an off-the-record media event.
But the two leaders "get along great," Trump had declared in May, following his first-face-to-face meeting with Turnbull.
Julie Bishop said she'd be taken aback by Trump's comments if they were directed at her. She declined to remark on his Twitter account
