In addition to working for Interscope as a songwriter, Lady GaGa began preparing the launch of her solo career. Her debut single, "Just Dance," was released to radio in April 2008, and her full-length album debut, The Fame, followed in August. Featuring fellow Akon affiliate Colby O'Donis, "Just Dance" took much of 2008 to catch on. The song debuted on the Billboard Hot 100 singles chart in August, at which time it had already become a massive club hit, but it didn't reach number one until January 2009. Internationally, the song proved similarly popular, reaching the Top Ten throughout much of Western Europe and beyond. In the wake of Lady GaGa's international breakthrough success with "Just Dance," the follow-up single, "Poker Face," was an even greater success, topping singles charts across the board, from the U.S. and Western Europe to Australia and New Zealand. Both songs were produced by Akon affiliate RedOne, who, along with Rob Fusari, co-wrote and produced much of The Fame, itself an international success in critical as well as commercial terms.
