The former Girls Aloud star will make a guest appearance in four episodes to be broadcast in the summer.
Harding will play a feisty character who will make life difficult for troublemaker Tracy Barlow, ITV has confirmed. Exact details about her storyline are not known yet but it is understood that her character could return.
The 33-year-old joins former Popstars alumna Kym Marsh in the cast, who has played Michelle Connor since joining the soap in 2006.
Many fans have questioned whether the announcement could be an April Fools, but ITV has confirmed that the news is true.
