The actress, 26, wrapped up warm this morning (29 November) to reveal the new and improved set based in Manchester.
Kym Lomas and Brooke Vincent were also present at the soap's new home, having moved from Quay Street to Media City in Salford which took two years to build!
It's the fifth incarnation of TV's most famous street.
Filming will begin there early next year, although Michelle will not have long left at the soap. She confirmed this week that her character Tina McIntyre will be killed off in 2014.
After helping to cut the red ribbon at the grand unveiling, Michelle tweeted: "The new Corrie set is amazing!!!! So strange, it's exactly the same but so different at the same time!! Hahah!"
Michelle recently told Jonathan Ross on his chat show that she is leaving the soap in May 2014, and planning a 2015 wedding to fiancé Mark Wright...
She made her first appearance as Tina in 2007.
