Gwen has had the better start, but i don't think Fergie is done yet. Her radio update is good and it's up to #55 on Itunes. If her video is good, it's going to push the song.
She kind of is destroying them both, but she has the best comeback single of the 3 so. Fair to note maybe that both BDL and L.A.Love have gotten promo and exposure during release week like frontpage iTunes banners and premieres on radio shows, while Big Hoops got nothing.
