If you haven't heard by now, nearly 5M #GMail accounts were leaked (although the list seems outdated) - which means Google Drive could have also been at risk, but with no celebrity leaks, I guess most celebrities prefer Apple? Of course, I kid.
Check via https://isleaked.com/ if your email address has been leaked. When I checked mine, my email address was there, but with an older password (based on the first 2 characters that were shown). So if you have and older password, change it now.
