As the girlfriend, and later wife, of the professional footballer Yannick Carrasco, Happart gained further media attention as a "WAG". Carrasco celebrated his goal in the 2016 UEFA Champions League Final by running into the crowd to kiss her, leading to international tabloid attention. The couple married in June 2017, with Happart accompanying her husband to China when he transferred to Dalian Yifang in 2018.
