The hip-hop star made the purchase at a Tesco store in Stoke-on-Trent after browsing shelves with a brunette, according to The Sun.
An onlooker told the newspaper: "It was Dappy without any doubt. He was flanked by two security guards. He had his trademark woolly hat on and dark shades. It was on Monday afternoon and the store was pretty quiet but people were looking at him.
"He entered the store with the brunette girl in tow and walked straight towards the health aisle. He then picked up a Clearblue pregnancy test."
It is thought that the woman who accompanied Dappy left the shop after realising that they were attracting attention, while the star went on to pay for the £8.99 test in cash.
