It's Iain Armitage like you've never seen him before: the star of "Young Sheldon" is returning to CBS via an episode of "Ghosts," Variety reports. The actor will appear as a "heightened version of himself" when he shows up to play a "high-stakes poker game at the mansion."

Armitage's episode is currently in production and is expected to air Thursday, April 16 (8:30/7:30c). 

In addition to his seven-season stint as the younger version of Jim Parson's Sheldon Cooper, Armitage also played Shailene Woodley's son in both seasons of HBO's "Big Little Lies."
