Former Made In Chelsea star Millie Mackintosh has claimed that Kate Middleton is in need of an image overhaul.

Speaking to the Mail on Sunday's You Magazine, the reality star and Quality Street heiress said that she would love to help the Duchess of Cambridge, who "wears too much eyeliner" and dresses like she is "middle-aged".

"I would love to give the Duchess of Cambridge a makeover. I think Kate wears too much eyeliner," she told the fashion publication.

Although Prince William's wife has topped best dressed lists across the globe, Mackintosh believes her style is too safe and ages her.

The 25-year-old continued: "She would look great if she toned down the eyes, wore some bright lipstick and mixed up her hairstyle - a scraped-back high pony would look fantastic.

"She'd look great in one of my little wrap dresses as she has such a gorgeous body and I think it would be fun - less middle-aged - and a bit sexier without being too revealing."

Meanwhile, the make-up artist and fashion designer, who will soon celebrate her one year wedding anniversary with husband rapper Professor Green, confirms she has turned her back on her reality TV days to focus on her new career.

"I am still in touch with some of the production people... they know I am not going back though. Stephen [Pro Green] and I often joke that some of the stuff that happens to us would make a pretty entertaining reality show, but why would we bring that stress into our life?"
