Which member of Destiny’s Child was Beyoncé’s longest-serving groupmate?

Kelly Rowland was Beyoncé’s longest-serving groupmate in Destiny’s Child.

Beyoncé and Kelly Rowland performed together in the group from its early formation in the 1990s until Destiny’s Child disbanded in 2006. The two had also been connected before the group became famous, having performed in earlier versions of the act during their youth.

Destiny’s Child’s best-known final lineup consisted of Beyoncé, Kelly Rowland, and Michelle Williams. It produced major hits including “Say My Name,” “Survivor,” and “Bootylicious,” and became one of the best-selling female groups in music history.

LaTavia Roberson and LeToya Luckett were original members but left the group in 2000. Michelle Williams joined later, in 2000, so she was a member for fewer years than Rowland. Beyoncé and Rowland have remained publicly associated as longtime friends and collaborators.
