Fox seems to love those from The Masked Singer, leading the network into bringing them on to Lego Masters, which is becoming a franchise this summer. Recently, news came that the singing competition series' host Nick Cannon is set to replace Will Arnett as host in the upcoming Lego Masters season 6, which premieres sometime in the 2025-2026 season for the network. Well, the network has tapped another alum to host its spin-off, Lego Masters Jr.
Get ready to see Kelly Osbourne leading us through the new and exciting show with cute youngsters putting their building block skills to the test. Osbourne is set to host Lego Master Jr., which premieres Monday, Aug. 18, 2025 at 8 p.m. ET on Fox. She'll be joined by judges Amy Corbett and Boone Langston.

Osbourne competed on The Masked Singer season 2 back in 2019. She was disguised as the Ladybug, and actually made it quite far. She was eliminated in week 6 out of 10 after performing "Youngblood" by 5 Seconds of Summer. The star has hosted or co-hosted other projects before, so she does bring experience. It will be interesting to see her take on these duties though, and how well the show will do.
According to Variety, the spin-off series will take place over four weeks with the juniors, ages 9 to 17, and their celebrity teammate working hard to build impressive designs for the judges. By the end, those who make it to the final round will be competing for the $50,000 cash prize, as well as the Lego trophy. And bragging rights of course!

The celebs coming aboard include actor Ravi Patel; actor, comedian, and Conan O'Brien's sidekick on his talk shows Andy Richter; American Idol alum Jordin Sparks, actress Alison Sweeney; and Real Housewives star Porsha Williams. I think that's a really good lineup of stars!
I think it's such a good idea that Lego Masters is getting a junior version of the competition series. Honestly, I'm surprised it took Fox so long to do it. Other shows like America's Got Talent, Master Chef Junior, and countless others have found success with doing a version of their shows with younger contestants. It's sweet and fun to watch, and some of these kids are just so talented. I love it when a franchise grows like this, and will definitely be tuning in.
Don't miss Kelly Osbourne hosting Lego Master Jr. when the series premieres Monday, Aug. 18, 2025 at 8 p.m. ET on Fox.
