British singer Adele has mastered the art of disguise - a shop worker failed to recognise the star when she entered a London design centre to browse for furniture.

The Rolling in the Deep hitmaker easily blended into the busy London crowd when she hit the streets with her one-year-old son Angelo, by appearing with no make-up and donning an oversized cardigan with leggings.

The star succeeded in hiding her identity with her low-key outfit as employees at London's Chelsea Harbour Design Centre failed to even notice the star.

One tells Britain's Daily Mail newspaper, "She came in looking for furniture and went into a couple of different showrooms, but she didn't stay long. I don't think she bought anything. I barely recognised her to begin with."
