Nicolina Giordani (1740 – after 1775), also known by the stage name La Signora Spiletta or La Spiletta, was an Italian opera singer.
A member of the Giordanis family from Naples,[1] she was the daughter of Antonia and Giuseppe Giordani, librettist and composer, and the sister of Francesco and Marina, both singers, and Tommaso, a composer and instrumentalist.[2] She performed in opera productions with her family's company in Northern Italy, Germany, Holland and France, before settling in London, where she was active between 1753 and 1774.[3] She became known by her stage name after a popular performance as the character from Gli Amanti Gelosi.[4] She was described by Thomas Gray as a singer "with the utmost justness of ear, the strongest expression of countenance, the most speaking eyes, the greatest vivacy [sic] & variety of gesture". She also received praise by Horace Walpole, who wrote that she "beats all the actors and actresses I ever saw for vivacity and variety".[5]
