The White House has named Australian Prime Minister Malcolm Turnbull as "the President of Australia" on its website.
The title was written in a press release about Trump's efforts to "make America safe again", dated February 4.
The gaffe comes just days after White House Press Secretary Sean Spicer appeared to call him "Mr Trumble" during a press conference.
"The President had a very cordial conversation with Prime Minister Trumble, where they went through an extensive discussion of this deal," he seemed to have said on Thursday local time.
'Trumble' began trending on Twitter in Australia.
On Sunday, 'President of Australia' followed suit.
