Kelly Rowland became Beyoncé’s longtime singing partner in Destiny’s Child before the group disbanded.
Rowland joined the group during its formative years, and the final trio consisted of Beyoncé, Kelly Rowland, and Michelle Williams. This lineup produced major hits including “Survivor,” “Say My Name,” and “Bootylicious.” Destiny’s Child became one of the best-selling girl groups in music history before ending its group career in 2006.
Rowland and Beyoncé remained closely associated after Destiny’s Child. Rowland also pursued a successful solo career, releasing albums such as Simply Deep and Ms. Kelly. She and Beyoncé have appeared together in performances and recordings, including Destiny’s Child reunions.
LaTavia Roberson and LeToya Luckett were original members who left the group before its best-known final lineup. Michelle Williams joined later and was part of the trio, so she is a plausible answer, but Rowland was the member most consistently paired with Beyoncé across the group’s entire rise.
