Manganiello and O'Connor began dating in September 2023, a source told PEOPLE at the time. Two months earlier, in July 2023, he and ex-wife Sofia Vergara announced that they were divorcing.

Sunday marks the first time the One Tree Hill star posted about O'Connor on social media, but the couple made their red carpet debut in December 2023 at the Children of Armenia Fund (COAF) Gala at Cipriani in New York City.
