Is the going to be a alivin and chipmunks 3?

As of my last knowledge update in September 2021, there has not been an official announcement regarding the release of Alvin and the Chipmunks 3. There have been two previous Alvin and the Chipmunks movies released in 2007 and 2009, both following the adventures of the singing chipmunk trio and their human friend, Dave Seville. Given the success of the first two movies and the popularity of the Chipmunks franchise, it is possible that a third movie could be in development. However, since I don't have access to real-time information, I suggest you check official sources or websites related to the Chipmunks to get the most up-to-date information.
