Sheldon and Leonard will be getting another visit from their mothers later this month, TVLine reports, when Laurie Metcalf and Christine Baranski return to The Big Bang Theory. Metcalf and Baranski are set to reprise their roles as Mary Cooper and Beverly Hofstadter - in the same episode!

The two will appear in the show's penultimate episode of the season, airing April 30. The outing marks the first time the two will visit in the same episode, though whether they will share any scenes is unclear.
