No count has ever been made. Nor is an accurate one likely.
Bridgit Mendler first began appearing on the Disney Channel. She made guest appearances on shows such as JONAS and Wizards of Waverly Place. This paved way for her to become the lead in Good Luck Charlie which has been successful since its debut. As is with all Disney girls, they are trained to be triple threats (acting, singing, dancing and/or songwriting). Bridgit's contract would have included a record deal with Hollywood Records, Disney's way of shoving acts like Miley Cyrus and Selena Gomez down the non-prepubescent public's throats. Thanks to the increased exposure as a result of Charlie, Bridgit was able to release an album.
