Jim Carrey and Jenny McCarthy have split ... and they just announced it themselves, in less than 140 letters each.
The comedian just posted the following on his Twitter: Jenny and I have just ended our 5yr relationship. I'm grateful 4 the many blessings we've shared and I wish her the very best! S'okay!
McCarthy tweeted about the breakup too: Im so grateful for the years Jim and I had together. I will stay committed to Jane and will always keep Jim as a leading man in my heart.
Jane is Jim's daughter from a previous marriage.
