I've heard Corrine pronounced both CO-RIN and CO-REEN, and I've heard Corinne pronounced both ways, also. But I personally think Corrine should be pronounced the CO-REEN way because of the two r's. Corinne should be pronounced CO-RIN because of the two n's.Examples: Corinne Bailey Rae pronounces it CO-RIN. But on Television show Strange Days at Blake Holsey High, there is a character names Corrine, played by Shadia Simmons, who also pronounces it CO-RIN. So it's a bit confusing.
