How do I remove icon from the launchpad if I already moved app to trash So, I had an app, and removed it (moved to trash)

Now, I can see its icon in launchpad (when I click it says "You can't open the application "Name" because it is in the trash.). With only button OK.

How do I remove it from Launchpad completely?
Emptying the trash would have worked as well. 
Launchpad shoes all apps it finds via spotlight, not just those who are in the Applications folder.
