Solange Knowles has quit working as a representative for her family's Dereon clothing brand.

The clothing line was launched in 2004 by Beyonce, her sister Solange and their mother Tina Knowles.

Solange, 24, said in a statement: "I initially was involved as the spokesperson, but the clothes just didn’t reflect my personal style and I decided to hand that over."

But according to gossip site Media Takeout, Solange's departure from the brand is actually because of her alliance with her father Mathew Knowles.

There's been rumours of a family feud ever since Mathew and Tina Knowles announced that they would be divorcing. Beyonce is apparently siding with her mother, while Solange is supporting their father.
