Allison Holker posted the message on Wednesday (21 December), just less than two weeks after Boss’s death was announced.
The longtime Ellen DeGeneres Show DJ was 40, and his death left the entertainment, music, and sports world in mourning.
DeGeneres led the celebrity condolences to the star, who first rose to fame as a contestant on MTV’s The Wade Robson Project.
In 2008, he came in second place on season four of So You Think You Can Dance. Later, he returned to the show as an All-Star, and again in 2022 as a judge.
Holker, who has three children with Boss, wrote on Instagram: “My ONE and ONLY Oh how my heart aches. We miss you so much.”
Their children are Zaia, three, Maddox, six, and Weslie, 14.
In 2014, Boss joined DeGeneres’s series as a DJ, where he became the talk show’s staple until its conclusion in June this year.
DeGeneres named him an executive producer of the show in 2020.
