“Big Bang Theory” spinoff, “Young Sheldon,” has officially been ordered by CBS.

According to TV Line, the network finalized the order for the “Big Bang Theory” prequel that will center on the life of a young Sheldon Cooper (Iain Armitage). The “Big Little Lies” breakout star will be joined by actress Zoe Perry, who will be playing the role of young Sheldon’s mom. In the original CBS sitcom, Sheldon is played by Jim Parsons, and his mom is played by veteran actress Laurie Metcalf. The latter happens to be Perry’s real-life mother.

Parsons will narrate the offshoot for “Young Sheldon.” The actor also serves as one of the executive producers of the new show. He is joined by his real-life partner, Todd Spiewak, as well as “Big Bang Theory” showrunners Chuck Lorre and Steve Molaro.

Meanwhile, there were rumors suggesting that “Young Sheldon” was being created to replace “Big Bang Theory.” After 10 seasons, CBS took some time before renewing the sitcom. Contract negotiations took place for several months before the network finally announced that the Kaley Cuoco-starrer will return for Seasons 11 and 12.

After the show’s renewal, Variety reported that Cuoco, Parsons, Johnny Galecki, Kunal Nayyar and Simon Helberg, who are each receiving $1 million per episode, offered to give Mayim Bialik and Melissa Rauch $50,000 each so they could also get a raise. Since joining the CBS sitcom in Season 3, Bialik and Rauch only receive $200,000 per episode. If the cast members’ offer will be approved, the actress will receive $450,000 per episode in Seasons 11 and 12. As of late, contract negotiations are also underway for the two actresses.

“Big Bang Theory” Season 10 airs Thursdays at 8 p.m. EST on CBS.
