I didn't know Katy eclipsed Gaga. I thought Gaga underperformed and went below her standards.
If Katy "eclipsed" Gaga that'd mean that she had iconic moments as the Meat Dress, VMA performance, Egg, Bad Romance etc. - No.
That means that she'd have outsold Gaga's best selling effort - No, not even her 2nd best selling.
That'd mean that she outsold Gaga's best selling singles - PF, Bad Romance and Just Dance remain unbothered.
And I don't have to bring tour gross of 500M nor Gaga's networth and power right ?
the moment Gaga goes above 3M albums sold WW with her next record, everyone will forget about Katy outperforming Gaga. Remember Beyonce ? after 4 ? How she was fading ?
