Michelle Connor (Kym Marsh) is to get a big surprise in an upcoming episode when boyfriend Steve's (Simon Gregson) study buddy Andrea turns up at the Rovers looking a lot more glamorous than he'd been making out.
Former Emmerdale and Dancing on Ice star Hayley Tamaddon will make her debut on Christmas Eve with Andrea set to make Michelle instantly jealous.
Coronation Street producer Stuart Blackburn said recently of Tamaddon's signing: "I'm absolutely delighted to welcome Hayley to the show. She's a great actress who I know is going to bring plenty of drama to the famous cobbles of Weatherfield."
As well as joining the ITV soap, Tamaddon will also be featuring in the all-star final series of skating competition Dancing on Ice, which is set to return in January 2014.
