It was a family affair for Solange and Beyonce Knowles at Coachella 2014.
Solange Knowles Danced With Beyonce at Coachella 2014
The festival crowd went into hysterics after Mrs Carter arrived on-stage to show off her dance moves. The Knowles girls didn't duet, but they really didn't have to - treating the crowd to a pretty awesome synchronised dance-off.
Beyonce's husband Jay-Z also made a surprise appearance at Coachella 2014, putting his decade-long feud with Nas to on-side for a stunning rendition of Dead Presidents II.
Solange is Beyonce's younger sister, and by 21 had already experienced both marriage and divorce.
"Luckily, I dated all of the losers ages ago. My love life has been stable for a while," she recently told Harper's Bazaar. Solange has been dating the video director Alan Ferguson since 2011.
"It's a f*****-up thing - without conflict it's a lot harder to write interesting songs," she added.
This year's Coachella Festival was headlined by the returning Outkast, Muse and Arcade Fire. It also featured performances from The Replacements, Queens of the Stone Age, Lana Del Rey, Foster the People, Lorde, Elle Goulding and Bryan Ferry.
Solange Knowles released a debut full album True on November 27, 2012. It was produced by long-time collaborator Dev Hynes, aka Lightspeed Champion, aka Blood Orange.
