The 28-year-old singer and 34-year-old recording artist attended the Balmain runway show Wednesday. Knowles and Rowland have known each other for years through the former's older sister, Beyonce Knowles, and her involvement with Destiny's Child.
Knowles and Rowland sat front row with rapper Kanye West and a newly blonde Kim Kardashian. Rowland shared a photo of herself laughing with Knowles on Twitter, and captioned the picture, "I [heart] my Solo! @solangeknowles #PFW."
