According to the source, the 52-year-old actor stayed at Amanyara Villas, a secluded luxury resort. He was joined by a male friend.
As for Pitt and Jolie's reported temporary two-day truce? The source says reports of Jolie inviting Pitt to Thanksgiving in Los Angeles are "not true."
The reports claim Jolie had allegedly called Pitt and told him that their six children -- Maddox, 15, Pax, 13, Zahara, 11, Shiloh, 10, and twins Knox and Vivienne, 8 -- were asking them to be nice to each other for the holidays. The reports also claim that Shiloh even wrote her parents an email, begging them to spend it together.
"Completely false," the source also told ET. "[Angelina] never called… [that's a] total lie."
"The reports that she refused to let him see them on Thanksgiving or originally called a truce and then went back on it are all false," another source explained. "They were never planning to see Brad on Thanksgiving per the schedule created by the children and the family therapist."
News of Pitt's trip comes just one week after the FBI closed its child abuse allegations investigation against him. The bureau confirmed they would no longer be investigating Pitt's alleged Sept. 14 plane incident, and that no charges would be filed.
"In response to allegations made following a flight within the special aircraft jurisdiction of the United States which landed in Los Angeles carrying Mr. Brad Pitt and his children, the FBI has conducted a review of the circumstances and will not pursue further investigation," the FBI said in a statement to ET. "No charges have been filed in this matter."
