This Pop-Rock singer topped the US Singles Chart in 2008 for the first time without having any collaborators on the track. It spent 1 week at #1. Name the artist and the very song that achieved this feat.
Hint: This artist topped the US Singles Chart, UK Singles Chart, and Australian Singles Chart in the Early 2000's, but this was a separate song and that song was a collaboration for a cover song with 3-4 other women (one of the women being a huge rap phenomenon and leading the production for the collaboration with Rockwilder). That song won a Grammy Award in the category of "Best Pop Collaboration with Vocals".
