The actress, who will appear in the next series of Dancing On Ice, is said to have finished the relationship just days before Christmas.
According to today's Sun, Samia found it difficult to handle the amount of time they spent apart because of work.
A friend of Samia told the newspaper: "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."
Samia - who lives in Cheshire with her daughter Freya, three, from her marriage to property developer Matthew Smith - confirmed: "We've split up - that's it."
Samia, 30, and dad-of-two Will, 34, fell in love on the set of Manchester soap Coronation Street, playing on-screen couple Maria Connor and bad boy Chris Gray. They've been together since January 2011.
She is paired with Frenchman Sylvain Longchambon, 32, in the new series of Dancing On Ice which starts on Sunday 6 January.
In a separate story, today's Sunday Mirror claims that professional ice skater Sylvain recently split from his Hollyoaks girlfriend Jennifer Metcalfe.
They got together in 2010 when they skated together on the ITV1 show.
