London, Apr 2: Designer Stella McCartney has revealed that raising her four children at the same time as running her fashion label leaves her regretful.

"I must admit that at times I feel overwhelmed," the Telegraph quoted the daughter of Sir Paul McCartney as saying.

"I feel guilty because I don't do either of the things well: neither work 100 per cent, nor being a mother 100 per cent," she added.

McCartney, 39, who is married to Alasdhair Willis, 40, a "creative consultant", gave birth to her second daughter, Reiley, last year.

As well as their four-year-old daughter, Bailey, they have two sons, Miller, six, and Beckett, three. (ANI)
