Dating & Relationship Status
As of recent updates, Johnny Galecki is married to Morgan Galecki. He has been open about his personal life, sharing details about his family and marriage in interviews.
His mother, Mary Louise "Mary Lou" Noon, was a mortgage consultant, and his father, Richard Galecki, was a member of the U.S. Air Force stationed in Belgium and worked as a rehabilitation teacher. Galecki is the eldest of three children with a sister, Allison, and a brother, Nick, who he describes as a "mechanical genius" in the automotive industry. Galecki grew up in Oak Park, Illinois. He dropped out of school after 8th grade, attending high school for only one day.
During an interview with New Zealand radio station ZM, Galecki recalled his childhood relationship with his mother. As a child, he was well known for making up long stories and tales. In such situations, his mother used to make him play the "quiet game", where he had to see how long he could go without talking. He also recalled that despite being a loving mother, she was also very tough. One phrase she would lovingly use was, "I love you, now get out."
During his run on Billy, Galecki began making guest appearances on the hit ABC sitcom Roseanne as the younger brother of Mark Healy (Glenn Quinn), who began a relationship with Darlene Conner (Sara Gilbert). Introduced in his first appearance as Kevin Healy, his name was soon changed to David. After a few more guest shots, Galecki was named a permanent Roseanne cast member from the fall of 1992 onward, after the cancellation of Billy. He would remain in the role of David Healy until the end of Roseanne's run in 1997, with the character eventually marrying Darlene and fathering two children with her. Galecki's character on The Big Bang Theory would also have a short-lived relationship with Gilbert's character on the same show.
Galecki played Leonard Hofstadter in the CBS sitcom The Big Bang Theory, which ran from 2007 to 2019 and was, for most of its run, among the top three most popular television comedies in the US. Galecki was originally asked to play the role of Sheldon Cooper, but he felt he was better suited for the role of Leonard, and Sheldon's role was eventually given to Jim Parsons. During the show's run, two of Galecki's former Roseanne co-stars appeared on the show: Sara Gilbert (as Leslie Winkle, Leonard's colleague) and Laurie Metcalf (as Mary Cooper, Sheldon's mother). Galecki is a cellist, a talent that was used on the show. Until 2013, Galecki and his Big Bang co-stars Kaley Cuoco and Jim Parsons each earned US$325,000 per episode. By 2014, the three were earning US$1 million per episode.
As a teenager, Galecki dated his Roseanne (and later The Big Bang Theory) co-star Sara Gilbert (their characters also dated). During their relationship, Gilbert came out as lesbian. They remain close friends.
While working on The Big Bang Theory, Galecki dated co-star Kaley Cuoco for about two years until December 2009 while the two also played a couple on the show. Cuoco told CBS Watch that they have remained on good terms since ending their relationship.
In 2018, Galecki started dating Alaina Meyer. In November 2020, it was reported that Galecki and Meyer had separated. He is now married to Morgan Galecki, who in 2024 gave birth to their daughter.
