Shippen was a close friend of British officer John Andre, whom she met in 1777 during the British occupation of Philadelphia, as her family would hold society parties, which he regularly attended. It is likely that the two had a romantic interest in each other early in their relationship - Shippen often referred to him in letters as her "dear friend."

Shippen met Benedict Arnold in the summer of 1778, and despite the fact that he was a commander in the Continental Army and that she came from a family of known Loyalists, Arnold began courting her. They married the following year.

Together with John Andre and Benedict Arnold, Shippen aided a spy ring leaking secrets of the Continental army to the British. Though it was Arnold who supplied the knowledge, Shippen helped by delivering messages, coding, handwriting them, and developing special invisible inks. It has been speculated by numerous historians that Shippen herself convinced Arnold to betray the Continental army, and Aaron Burr published accounts of conversations and letters sent to him that certainly sustain, if not prove, this theory. The link is obvious - Shippen was a close friend of Andre, whom Arnold eventually delivered the information to. The two men had not known each other prior to their mutual friendship with Shippen.

George Washington uncovered Arnold's treason, and went to meet him personally at his house to confront him. Arnold fled, and Shippen herself pretended hysterics in order to establish a pretense that she had not been involved.

Shippen was the grand-cousin of William Shippen.

The house that Shippen lived at with Arnold would later become the home of William Howe, 5th Viscount Howe.

Shippen visited with Queen Charlotte of Mecklenburg-Strelitz in 1782, who agreed to give her a salary of 100 pounds annually. In addition, George III gave her 350 pounds, for her "meritorious" services to England.

Shippen was an acquaintance of Aaron Burr.
