In 2007, Rowland, along with stars such as Jessica Simpson and the cast of Grey's Anatomy autographed pink Goody Ouchless brushes that were made available for auction on eBay, with all proceeds going to Breast Cancer Awareness. Also, the singer teamed up with Kanye West, Nelly Furtado, and Snoop Dogg to design a Nike sneaker for another eBay auction. All proceeds went to AIDS Awareness. In October 2007, Rowland auditioned for the role of Louise, Carrie Bradshaw's assistant, in the 2008 film adaptation of HBO's comedy series Sex and the City. The part eventually went to Jennifer Hudson. Two months later, Rowland appeared as a choirmaster in the first season of the NBC talent show Clash of the Choirs among other musicians such as Michael Bolton, Patti LaBelle, Nick Lachey, and Blake Shelton. Rowland's choir finished fifth in the competition, and Clash of the Choirs did not return for a second season.
