The Saturdays star was out and about with bandmate Una Healy, as reports claimed that she and Harry are in the early stages of dating after first meeting two years ago.
Paparazzi caught up with the blonde singer yesterday afternoon - as seen in the video below - taking the opportunity to question her about the claims.
However, King ignored their attempts and continued to walk past them. Smiling as her friend refused to respond, Healy also remained quiet.
King also bypassed the topic on Twitter, making only one tweet on her account yesterday, in which she asked: "Anyone else STILL tucking into their easter eggs? ;-) (sic)"
An alleged friend of Harry, 27, told the Daily Express that the couple were "head over heels" in love, and had attempted to keep their new relationship private.
