“It’s three o’clock in the morning … do you know where your governor’s lover is?”

Obviously, that’s not how that expression goes, but Maria Belen Chapur – the Argentine beauty who made international headlines earlier this summer when S.C. Gov. Mark Sanford admitted to having an affair with her – could be closer than you think.

Much closer.

In fact, sources tell FITS that Chapur has been in South Carolina for “several days” now, first staying at a guest house on the governor’s Coosaw Plantation in Beaufort County and most recently staying at “a friend (of the governor)’s house in Columbia.”

That progression would certainly fit with what we know of the governor’s schedule over the past few days. Sanford spent last weekend on his plantation in Beaufort County before returning to Columbia on Monday evening for meetings with constituents.

On Wednesday, Sanford denied a report published here on FITS that he was “contemplating” moving Chapur into the Governor’s Mansion, which was vacated last Friday by S.C. First Lady Jenny Sanford and the couple’s four boys.

While issuing his denial, however, Sanford refused to give a straight answer as to whether or not he had been communicating with Chapur.

Could this be why?

According to his public schedule, Sanford leaves today for a weekend of Air Force Reserve duty in Panama City, Florida.
