Hated it on the initial listen and now I can't get that chorus out of my head.

The video ist great and so was their performance

But I got to be honest, as much as I like them and think that they are amazingly talented, "Drink my ..." is correct. They are such a prominent girl group and are existing for nearly a decade, yet they don't have an amazing catalogue like Sugababes or Girls Aloud. PCD had more classics with one album than they have with 5 (?).
