In a sit-down interview with CBS’ The Early Show, songstresses — and sisters — Solange Knowles, 22, and Beyoncé talked music, family and where they see themselves in 10 years. Calling her sister an "amazing songwriter and performer," Beyoncé, 26, nonetheless said it’s Solange’s 3 ½-year-old son Daniel Julez who will continue to define her sister’s life. "[Solange] is a mother first," Beyoncé explains. It’s that dedication to motherhood that Beyoncé, who married rapper Jay-Z in April, says she hopes to learn from someday.

Julez is Solange’s son with ex-husband Daniel Smith Jr. Her new album Sol-Angel and the Hadley St. Dreams is in stores now.
