ITV announced on Monday night (19 August) that the Tommy Duckworth actor's contract had been terminated after Chris was unmasked as the man behind a rapper called The Phantom, who posted offensive rap videos to YouTube referencing rape and violence.
In a statement, Chris said: "I completely understand that ITV had no choice but to terminate my contract today. I have had two wonderful years playing Tommy Duckworth with only happy memories of my time on Coronation Street.
"I am mortified that I have brought so much embarrassment to my colleagues and employers these last few days. My biggest regret however is not to do with losing my job, but that I have hurt and let down so many people including those in a vulnerable situation and I am so very deeply ashamed of this."
Chris, 25, continued to say there was "absolutely no excuse" for his actions and he takes "complete responsibility" for what has happened.
He added: "They were in no way thought out or represent at all my attitude towards women, rape and violence. I just want to apologise from the bottom of my heart to everyone who I have offended or upset.
"I am also mortified to have put my mother, grandad and girlfriend through the last few days which they are hurt and bewildered by and so do not deserve. I am so sorry. Once again to everyone who I have let down and hurt. I am deeply sorry."
The videos are no longer available on YouTube.
Prior to appearing in Corrie, Chris found fame playing Justin Burton on Hollyoaks and appeared on Dancing On Ice.
