The heavily tanned ex-Prime Minister and his wife Cherie posed with Maltese leader Joseph Muscat during a trip to the Mediterranean island.
Mr Muscat, a stanch Europhile, tweeted: “It was a pleasure hosting Tony and Cherie Blair and sharing so many insights with them.”
Like Mr Blair, he has called for a second EU referendum to be held to halt Britain’s impeding exit from the bloc.
In a remarkable interview with a Dutch newspaper two weeks ago, the Maltese PM claimed Brexit may never happen.
He said: “For the first time, I’m starting to believe that Brexit will not happen. I am seeing hopeful signs that indicate things will change.
“I see encouraging signs that the tide is turning. I’m not saying the Brits have made a mistake, but the mood is changing.”
His comments echoed those made by Mr Blair when he last month claimed it is “possible now that Brexit doesn’t happen”.
The millionaire former Labour Party PM said the prospect of the UK quitting the bloc was “doing us damage economically [and] politically.”
Speaking to Sky News, he insisted: “I think public opinion is moving on it.”
But he was lambasted by Brexit campaigners, with Nigel Farage saying: “Mr Blair, perhaps you weren’t listening, but our answer was we want to govern ourselves.”
Last November, Mr Muscat warned Britain could be “bashed” by Brussels officials in Brexit negotiations.
He said: “I know that there is absolutely no bluffing from the European side, saying: ‘We will start in this position and then we will soften up’.
“No, this is really and truly our position and I don’t see it changing.
“In the UK it’s fair game to bash Brussels and then you don’t need to be surprised if in Brussels they bash you back.”
According to newspaper Malta Today, Mr Blair and his wife “strolled casually” around the streets of capital city Valletta before the meeting.
The couple and a “bevy of security guys in black suits” were later spotted attending mass at Mdina Cathedral.
Mr Blair told Malta’s state broadcaster: “I wanted to come here to see Malta again and to meet the Prime Minister.
“It was not too difficult to come here since we were in Italy.”
A spokesman for Mr Blair refused to reveal any details of his talks with Mr Muscat when contacted by Express.co.uk this afternoon.
