One of the most surprising visitors president-elect Donald Trump had on Wednesday was none other than boxing champion Floyd 'Money' Mayweather Jr.

Since Trump won the presidential election last week, dozens of politicians and businessmen have been spotted entering Trump Tower for visits with the billionaire.

But Mayweather is the only athlete who has so far been seen visiting the Republican.

The 39-year-old five-division world champion was photographed standing in-between the new president and his son, Donald Trump Jr., at an office inside of Trump Tower.

The photograph, which shows the trio smiling, was shared to Twitter by Trump Jr. on Wednesday night.

'Had a great visit from @FloydMayweather today with @realdonaldtrump. One of the best all time boxing legends,' he wrote.

It's unclear who Mayweather voted for during the election, as he never formally endorsed Trump or Hillary Clinton for president.

It's also unknown what the men discussed, but Trump is known to love boxing.

He sat ringside with his wife Melania at the historic fight Mayweather had against Manny Pacquiao. Plus, Trump is said to have a close relationship with boxing promoter Don King and retired boxer Mike Tyson.

Mayweather, who often boasts on social media about how much money he has with lavish trips, fancy cars and just stacks of dollar bills spread out on social media, has made $700million in career earnings since turning pro in 1996.

While in New York on Wednesday the boxing promoter announced the upcoming Super Middleweight World Title Unification bout with WBC Super Middleweight World Champion Badou Jack, of Sweden, against IBF Super Middleweight World Champion James Degale of Great Britain.

Mayweather was just one of many people who visited Trump Tower on Wednesday to see the billionaire businessman.

Political and business elites as well as several family members were spotted walking in and out of the building since last week.

Many are having meetings with Trump as the President-elect's transition team helps decide who will be by his side in the White House.

While Trump's camp have not yet revealed the choices he's made for his Cabinet, several politicians and businessmen, including former rival Ted Cruz and New York Mayor Bill de Blasio, have made appearances at Trump Tower.

Vice president-elect Mike Pence took over the transition leadership for Trump's journey to the White House from Chris Christie last week and together they have been 'reviewing a number of names for key jobs' as lists for the leadership positions begin to narrow, Trump spokesman Jason Miller said.
