-- The war of words between former Mexican President Vicente Fox and Donald Trump has reached a new level: selfies.
Fox posted a photo of himself in Cancun on Twitter with the bright aquamarine water and sandy beach in the background. His message to the Republican front-runner was loud and clear.
This is not the first time the former president, who left office in 2006, has verbally sparred with Trump.
Trump said his proposal to build a wall along the U.S.'s southern border will be paid for by the Mexican government.
During an interview with Fusion's Jorge Ramos in February, Fox said: "I am not going to pay for that f------ wall."
