Please help me, driving me insane

There is a song from a few years back sung by a girl group from Europe (mainland) I do not know the words as such but it sounds like ''I said a hey hah a hey a....'' ending the chorus with what sounds like ''guadalupi'', in the video they have the words running along the bottom of the screen, please help me with this I love the song but can't work out what it is, thanks Robert

My guess would be ....

Las Ketchup - "Aserejé" (The Ketchup Song)
