Actually, those two backup singers/dancers are the not the same as used in CDL 02-03. These two are dancers that have appeared in almost all of her tours/cdls. When I first saw 'ourselves' performed live, I recognized them. I think it's strange she's using backup dancers as backup singers. And she does act a bit strange when performing this, seems like she's "bumping and griding" with the backup singers/dancers.
