In late 1734, Hedvig Taube conceived again, and this time, she left her position at court and was installed at a private residence the king had arranged for her close to the royal residence of Wrangel Palace awaiting her delivery, where he regularly visited her by litter. On 17 March 1735, she gave birth to a son by the king in her residence, which were given the king's brother William of Hesse as his godfather and promised the title count of Hesse, while Hedvig Taube were given an allowance of 12.000 dlr from the state of Hesse, where the king was ruling Landgrave. All this made the relationship between the king and Hedvig Taube exposed in public and unable to conceal and herself the first acknowledged royal mistress in Sweden, which resulted in a public scandal. After her public acknowledgement and first appearance at court in 1735, the queen protested by claiming to be indisposed and refused to leave her rooms. After this snub, Taube never appeared at court again.
