Singer Jennifer Hudson has recorded a new duet featured in a commercial for Weight Watchers, belting out a tune alongside an image of her heavier self.

Creatively using footage from a 2004 performance on American Idol, the new commercial pits the old Hudson up against her newly slim self to perform the Whitney Houston classic โ€œI Believe in You and Me.โ€

Hudson became a Weight Watchers spokesperson in 2010. The singer drew media attention after successfully shedding more than 80 pounds.

The company opened a Weight Watchers center named after Hudson in her hometown of Chicago in September.

โ€œWeight Watchers has helped make my new lifestyle a reality by teaching me the tools I needed to be successful,โ€ Hudson said in a statement at the time of the facilityโ€™s debut. โ€œI hope this center and my story continue to serve as an inspiration to others to begin their own journey toward a healthier lifestyle.โ€

Hudson detailed her weight loss in a book, โ€œI Got This: How I Changed My Ways and Lost What Weighed Me Down.โ€

According to ABC News, Hudson writes that she turned down the lead role for the Oscar-winning film โ€œPrecious,โ€ claiming that after gaining weight for her role in โ€œDreamgirls,โ€ she wanted to appear in a film that had nothing to do with her weight.
