 ### Fixes
 
+- `[expect]` Adjust typings of `lastCalledWith`, `nthCalledWith`, `toBeCalledWith` matchers to allow a case there a mock was called with no arguments ([#12807](https://github.com/facebook/jest/pull/12807))
 - `[@jest/expect-utils]` Fix deep equality of ImmutableJS Lists ([#12763](https://github.com/facebook/jest/pull/12763))
 - `[jest-core]` Do not collect `SIGNREQUEST` as open handles ([#12789](https://github.com/facebook/jest/pull/12789))
