The Masked Singer semi-finals: Clock finally revealed as Grammy-winning singer

The longtime hitmaker joins the list of unmasked celebrities on Season 11.

FOX’s The Masked Singer revealed another mystery singer on Wednesday night. 

Grammy-winner Thelma Houston was behind the mask of the Clock, surprising the panelists and audience alike.

Houston, known for her iconic hit “Don't Leave Me This Way,” delivered a show-stopping performance before being unmasked. Only Rita Ora correctly guessed Houston's identity, with the other panelists offering names like Stephanie Mills and Janet Jackson.

Clock's elimination leaves Gumball and Goldfish to battle it out for the Season 11 championship next week. The semi-finals episode also featured electrifying performances from both finalists, each offering clues about their past careers through their song choices and pre-taped packages.

In the latest episode's standout performances, Goldfish – the Group A winner – belted out “You Oughta Know” by Alanis Morissette, dropping hints about her Disney past and love for performing.

Gumball, Group B's champion, sang “I Lived” by OneRepublic, sharing a message about his passion for music and his role as a father.

Clock, ultimately revealed as Thelma Houston, opened up about overcoming stage fright before delivering a powerful rendition of “Dancing in the Streets” by Martha and the Vandellas.

The Season 11 finale airs next week on FOX.
