Maria Menounos, Este Haim and more celebrities have more than one reason to celebrate New Year's Eve: It also happens to be their wedding anniversaries. Menounos tied the knot with longtime partner Keven Undergaro in December 2017 while hosting Fox's live New Year's Eve broadcast. "Finally some good news for mom. We are getting married tonight in Times Square!" she wrote via Instagram several hours earlier. "I will be the coldest bride ever but the happiest! Seeing my parents happy means everything." Menounos and Undergaro, who got engaged in 2016, exchanged vows shortly before the Times Square ball dropped to ring in the new year. TV host Steve Harvey officiated the ceremony in front of Menounos' parents. (Her mother died in 2021 after a lengthy battle with cancer.) Haim, for her part, got married on the 2025 occasion in a star-studded California celebration.
