In an interview with the Evening Standard, Christopher Bailey, Burberry's creative director said reports the fashion label were dropping Moss were nonsense.
"There has been so much nonsense in the press about Burberry dropping Kate -- it really is all nonsense," he said.
Moss has starred in nine out of 16 of Burberry's campaigns since 1998.
Bailey goes on to call the 31-year-old supermodel, who has just completed a month of rehabilitation in an Arizona clinic after the Daily Mirror printed pictures of her snorting cocaine, as "part of our family" and "one of the best models in the world".
"Is Kate still part of our family? Absolutely," Bailey said.
"Yes, she has some issues that she probably needs to resolve, but don't we all? She's living in the public eye -- but she's a model, and she's probably the best one ever in the world. And she's a good, good person inside."
Bailey also praises Moss for being a complete professional.
"She has always been incredibly professional -- and that girl works, she really works," he saud.
Bailey also quashed rumours that Jude Law's on/off girlfriend and 'Alfie' star Sienna Miller is set to fill Moss's shoes.
"No, Sienna is not in the new ad campaign. We can definitely say that."
Following the publication of the Mirror's pictures, Croydon-born Moss issued a public apology in an attempt to stem damage to her career, and vowed to sort out her life.
She reportedly lost up to 拢4m in earnings, with the loss of several lucrative contracts including H&M and Chanel.
At the time of the allegations, Burberry said it had never had a contract with the model, simply that Moss had worked on various projects, with one due for the autumn that was "mutually" decided by Moss and the fashion house would not go ahead.
Since coming out of rehab, Moss has appeared on the front cover of Vanity Fair and is set to guest edit French Vogue.
Famed photographer Mario Testino has come out in support of Moss saying she is not "tormented, torrid or depressed" and should not be judged by 10 minutes of her life.
This week, Moss packed up the contents of her 拢2m St John's Wood house and moved to her country farmhouse with daughter Lila Grace, reportedly to escape her hedonistic London lifestyle.
