See pics of Jim Parsons' and Mayim Bialik's return in 'Young Sheldon' finale

Jim Parsons and Mayim Bialik are reuniting for the series finale of "Young Sheldon."

Parsons and Bialik will reprise their "Big Bang Theory" characters, Sheldon Cooper and Amy Farrah Fowler, for the CBS spinoff’s finale on May 16. The network released first-look photos of their appearance on May 6.

The two actors last appeared on screen as their characters, who tied the knot in Season 11 of "The Big Bang Theory," in the sitcom's May 2019 series finale.

"Young Sheldon," a "Big Bang Theory" prequel starring Iain Armitage, Zoe Perry, Lance Barber, Annie Potts and Montana Jordan, tells the story of the brilliant Sheldon's younger years in small-town Texas.

Parsons has narrated the sitcom since its 2017 premiere and serves as an executive producer. Bialik has appeared in the series in two episodes as a voice-over.

The initial announcement of Parsons' and Bialik's on-screen reunion in March came just a day after CBS shared that “Young Sheldon” is getting a spinoff of its own.

The half-hour comedy, titled "Georgie & Mandy's First Marriage," will follow the lives of Sheldon's older brother Georgie (Montana Jordan) and his fiancée, Mandy (Emily Osment), “as they raise their young family in Texas while navigating the challenges of adulthood, parenting and marriage," the network has said.

Osment also shared the news on her Instagram page, writing, “Stick around y’all, the story continues…”

“Georgie & Mandy’s First Marriage” will air on Thursdays beginning in the fall.
