Donatella Versace has rubbished the efforts of celebrity designers claiming they are no competition to her.
The 55-year-old Italian - who took over as creative director of Versace after her brother Gianni was murdered in 1997 - has slammed a "lack of creativity" in lines designed by famous stars.
She said: "I think it is more a question of marketing. Some of these collections are for cheaper, mass market fashion. I don't think that creativity is there.
"You need to live among real things, you need as much information as possible."
While Donatella did not single out any famous person in particular, there are a number of celebrities with their own clothing lines including Victoria Beckham, Gwen Stefani, Katie Holmes and Jessica Simpson.
Although she's not a fan of celebrity designers, Donatella - whose famous fans include January Jones and Angelina Jolie - has previously revealed she is worried that young designers find it difficult to get started in the industry, saying: "Since the big fashion groups started, of course, it's harder for young people to get started. Now you talk about merchandising, marketing, where to put a product, how much it should cost, entry prices, and for someone straight out of college, that's scary. I think that the pushing of the commercial side of fashion over the past 10 years has maybe killed creativity a little - I'm talking generally here - but that may be changing again now."
