Fox Taps Kelly Osbourne to Lead ‘Lego Masters Jr.’ Debuting Aug. 18

Fox has named Kelly Osbourne as host of “Lego Masters Jr.,” a four-week competition that will debut in prime time on Aug. 18. The spinoff pairs teams of builders aged 9–17 with celebrity partners—including Andy Richter, Jordin Sparks, Porsha Williams, Ravi V. Patel and Alison Sweeney—to construct elaborate Lego creations judged by brickmasters Amy Corbett and Boone Langston. The winner will take home a $50,000 prize, a Lego trophy and the inaugural “Lego Masters Jr.” title. The commission extends Fox’s relationship with the Lego Masters format, whose fifth U.S. season is currently on air. The franchise is also expanding overseas: French broadcaster M6 relaunched the main series for a fifth season on July 7, highlighting continued demand for family-focused Lego competitions across markets.
