In 1723, the queen convinced the king to give his consent to the Prussian-British marriage alliance. In October of that year, they hosted a visit by George I in Berlin, who inspected Wilhelmine and agreed to the double marriage alliance if it was approved by Parliament. One day, Frederick William went to visit George I in Goehr. Sophia Dorothea did not accompany him, because she gave birth unexpectedly just before they were to leave. Sophia had been unaware of her pregnancy, leading to a rumor that she had tried to hide it. This caused Frederick William to suspect her of adultery. Upon his return, he had to be prevented from beating her by her chief lady-in-waiting, Sophie de Kameke, who held his arm and told him "if he had only come there to kill his wife, he had better have kept away." The king questioned the physician Stahl, his regimental surgeon Holzendorf, and de Kameke about the queen's suspected adultery, upon which de Kameke told him that "if he were not her king she would strangle him on the spot" for his accusation, which resulted in him making an apology to the queen and dismissing the affair.
