Matthew Protheroe (born 31 December 1989), known professionally as Vince Kidd, is an English singer who was a finalist on the first series of The Voice UK. In 2018, he began releasing music under the name billy blond. In 2023, he became a member of the duo, Blond & Redshank.

Appearing on the second of four audition shows, Kidd auditioned with "Like a Virgin", originally by Madonna—with all four coaches electing for him to join their teams; from which Kidd selected Jessie J. During the battle rounds, Kidd sang "We Found Love" by Calvin Harris & Rihanna against seventeen-year-old Jessica Hammond—with Jessie crowning him the winner. In the second live show, Kidd performed Elvis Presley's rendition of "Always on My Mind"—proceeding to the next round on account of the public vote. In the fourth live show, Kidd performed Whitney Houston's "My Love Is Your Love"—proceeding once again to the next round on account of the public vote. In the semi-finals, Kidd performed "Back to Black" by Amy Winehouse—advancing to the final. In the final of The Voice UK, Kidd performed both "Many Rivers to Cross" and "Nobody's Perfect"—the latter alongside coach Jessie J—ultimately finishing in fourth place.

Following The Voice UK, an eight-track compilation was released in June 2012 featuring Kidd's renditions of "Like a Virgin" and "Always On My Mind"; entering the UK chart at number ninety-seven and one-hundred-and-thirty-four respectively. Vince released his debut extended play—Sick Love—in the United Kingdom on 4 November 2012; which peaked at number one-hundred-and-ninety-eight on the UK chart.
