Here are the first photos of the 24-year-old Colombian hooker whose encounter with Secret Service agents caused the biggest sex scandal in agency history.

The single mom, who has only been identified as Dania, said she was stiffed by cheap agents who only wanted to pay her just $30, not the $80 she had asked.

“I tell him, ‘Baby, my cash money,” the woman was quoted by The New York Times.

One of the agents, she said, cursed at her and tossed her out of the hotel.

The hooker said she agreed to $250, the amount she gives her pimp. and the agent only forked over $225.

The photo comes as it was revealed this morning that the agents did their own sexy advance work — booking a hotel party space for prostitutes in Colombia before hitting the town to scout local pros, according to a new report.

President Obama’s men made reservations for a party room, big enough to hold 30 people, at the Hotel Caribe in Cartagena, and then hit a local brothel, ABC News reported today.

The boom-boom room bombshell shows that disgraced agents were getting the lay of the land, in advance to long night of fun.

After booking hotel party space, Secret Service Agents and military aides — tasked with advance work for Obama’s trip to Colombia — visited the “Pley Club” where they pounded top-shelf whiskey and enjoyed sexual services from working gals, ABC reported.

The men reportedly brought Pley Club hookers and other ladies of the night, picked up at other hot spots around town, back to Hotel Caribe.

That’s where at least one of the ladies and American Johns bickered over her payment, leading to police to his hotel room and blowing the lid off the agents’ naughty night.

At least three Secret Service agents have lost their jobs over the embarrassing incident.

Meanwhile, the Secret Service is moving quickly to quell the prostitution scandal.

“It’s certainly not over,” said Rep. Peter King (R-NY), chairman of the House Homeland Security Committee, which oversees the Secret Service.

The Secret Service did not identify the agents being forced out or eight others who remain on administrative leave. In a statement, the service said one supervisor was allowed to retire, and another will be fired for cause.

A third employee, who was not a supervisor, has resigned.

The two supervisors are in the agency’s uniformed division; one is a sergeant, according to a person familiar with Secret Service operations and refused to be identified because he was not authorized to discuss the matter.

The team under investigation includes members of the agency’s “jump teams,” which are sent to sites ahead of the president’s arrival to set up security. Others involved are on counter-assault and counter-sniper teams. The majority of those involved are believed to be based in the Washington area.

Secret Service Director Mark Sullivan has offered the agents under investigation the opportunity to take a polygraph test, though the agents can refuse.

The agents were implicated in the prostitution scandal in Colombia that also involved about 10 military service members and as many as 20 women. All the Secret Service workers who were involved had their security clearances revoked.

The scandal erupted last week after 11 Secret Service agents were sent home from Cartagena, on Colombia’s Caribbean coast, after a night of partying that reportedly ended with at least some of them bringing prostitutes back to their hotel. The special agents and uniformed officers were in Colombia in advance of Obama’s arrival for the Summit of the Americas.
