Terceira Metade (English: Third Half) is a Brazilian dating reality series created and produced by Globoplay in partnership with Boxfish, which premiered on July 18, 2025.
Hosted by Deborah Secco and featuring guidance from sexologist and author Regina Navarro Lins, the show follows committed couples open to expanding their relationship, who are joined by single participants interested in becoming part of a throuple.
Format In the first stage of the experiment, all cast members live in a beachfront house, where initial connections begin to form between the couples and potential third partners. Once trios are established, they move in together, sharing the same space and daily routine. In the final phase, each trio must decide the future of their relationship: continue as a throuple, return to life as a couple, or part ways entirely.
Cast The original 17 cast members were revealed on July 7, 2025, by Globoplay. The lineup featured four couples and nine singles. In episode 4, three additional singles and one couple joined the experiment, bringing the total number of housemates to 22.
