The pair tied the knot at Nunsmere Hall Hotel in Cheshire last month after being engaged for over two years.
Writing on Twitter today (October 3), Kym told fans: "So I've decided to change my name officially to Kym Lomas. Won't be on the credits for Corrie for a few weeks as we film 6 weeks ahead."
The actress's soap character Michelle Connor has more tough times ahead in the coming weeks as she will soon hear that her son Ryan is expecting a baby with scheming Tracy Barlow.
To make matters worse, Ryan will also be involved in dramatic car accident scenes airing later this month.
Kym and Jamie first became an item in 2008.
