The 30-year-old actress broke up with Thorp, 35, before Christmas.
The couple's characters, Maria Connor and Chris Gray, were also an item in Coronation Street.
Ghadie and Thorp began a relationship just weeks after ending their real-life marriages to other partners early in 2011.
The time they have spent apart because of work commitments has reportedly proved too difficult for the pair.
Sources told The Sun: "She's had enough and decided to call time on the relationship. Both she and Will were obviously a bit upset because it was just before Christmas. But now she's really happy being single and is ready to mingle again."
Ghadie confirmed: "We've split up - that's it."
The soap star is paired with Sylvain Longchambon, 32, in the new series of ITV1's Dancing on Ice, which starts on Sunday, January 6.
