Duchess of Cambridge pictured at Sainsbury's, where she 'bought Halloween bits'

The Duchess of Cambridge has been spotted shopping in Sainsbury's in Hardwick, Cambridgeshire.

Duchess Kate, 37, was pictured, together with Prince George, 6, and Princess Charlotte, 4, by a supermarket customer at the checkout. The royal wore a black polo neck and had her hair pulled back in a chignon as she made her purchases.

Mum-of-four Kathy Whittaker, 53, said of the celebrity spot: “Another shopper said that Kate was in the shop near the clothing and pointed where she was to me. I just couldn't believe it.”

"She was with Charlotte and George looking at Halloween outfits but her bodyguard was kind of watching people with phones and telling them no pictures.

"I managed to get the photo as she was at the self service check out.”

She added: "I didn't see what she actually bought. The lady that told me she was there had children with her and she said Kate was asking her children what they were going to be for Halloween.
