The Strokes star Julian Casablancas has thanked fans for their support following the death of his father, modelling industry mogul John Casablancas.

Casablancas, the co-founder of Elite Model Management, passed away in Rio de Janeiro, Brazil earlier this month (Jul13) after a battle with cancer and the singer took to his page on Saturday (27Jul13) to thanks devotees for their words of comfort.

He writes, "Thanks for all the kind words. It's been a tough two weeks."

The musician also shared a link to an emotional letter penned by his mother Jeanette Christiansen, who encouraged Casablancas to set up his modelling agency.

She writes, "A lot has been said and a lot has been written about John and about this business. Some of it true and a lot of it untrue. I backed Johnny 100 per cent when he wanted to change... the modeling (sic) industry. He stood up for women and fought for them to earn more so they could make fruitful careers... I am saying good-bye, dear John. I am so thankful for the years that we had together and for our son Julian."

The letter also states that Casablancas was laid to rest in Rio de Janeiro on Saturday (27Jul13) in accordance with his wishes.

Casablancas is credited with "inventing" the supermodel and helped launch the careers of numerous high-profile models including Cindy Crawford, Naomi Campbell, Linda Evangelista, Heidi Klum and Claudia Schiffer.
