The Penthouse 4 (U.S.)

The Penthouse 4 (also known as The Penthouse: Battle of the Exes) is the fourth season of the reality competition series The Penthouse. The season was promoted as the biggest season ever. After continued ratings growth, the season was extended to ten weeks, from the show's traditional eight week format. In addition, fourteen contestants competed in the competition, the most in a season to date.

The season's biggest twist was that, for the first time ever, contestants would not pick their teams in a schoolyard pick on Day 1. Instead, teams were predetermined by production, and each contestant was pitted against their ex.
