Perhaps the biggest star of "Good Luck Charlie," other than Charlie herself, was Teddy Duncan, played by Bridgit Mendler. Teddy was the one talking to the camera in most of the video diaries, and tried to give her little sister as much good advice as she could. Teddy's personal life was often the center of the plot on "Good Luck Charlie," and Mendler played the role perfectly.
So, where is Mendler today? After her stint on "Good Luck Charlie" came to an end, Mendler continued to act and sing, appearing in a few different television shows and music videos. But one of Mendler's biggest life changes since "Good Luck Charlie" ended is that she fell in love and got married. Mendler married her fiancé, Griffin Cleverly, in October 2019 at a private and intimate beach wedding, according to People. Additionally, Mendler starred in the Netflix holiday-themed limited series "Merry Happy Whatever" in 2019, and got to act alongside Dennis Quaid, which she said she really enjoyed. Clearly, Mendler is moving on up in the world, and "Good Luck Charlie" was just the beginning.
