Scherzinger said to the 21-year-old singer: "I want to see what your life was like before this."
Wearing the supermarket's uniform, Scherzinger got to grips with a piece of equipment that identified levels of stock, saying: "I've never done this, this is exciting!"

Douglas joked about the experience, saying that "going back [to ASDA] with Nicole was odd. She did enjoy it to the point where I thought, future prospects...". He also added that he believed Scherzinger was the "perfect mentor".
In the aisle of ASDA, Scherzinger also announced on the shop's PA: "If you vote for Jahmene this weekend, everything is half off in the store."
