This thread and nickname is in response to Gaga getting a DIAMOND certified SINGLE yet you are bringing up albums. Gaga holds a diamond album in France, so she does indeed have a diamond album to her name as well as a diamond single.
And? Doesnt change the fact that Gaga was the first doing it with a single.
Plus Gaga has a diamond album WW so it's not like she didn't achieve something similar with her albums.
