On Tuesday, editors at People published images showing the Australian singer-songwriter tying the knot with her boyfriend Dan Bernad. According to the publication, Sia and Dan exchanged vows in an intimate ceremony held at Domenico Dolce and Stefano Gabbana's Villa Olivetta in Portofino, Italy over the weekend. One snap showed Sia, 47, wearing a gorgeous blush-pink lace gown, while another sees her and Dan exchange rings under a floral arch. Representatives for the notoriously private Chandelier hitmaker have not yet commented on the happy news.
