Here's one I actually didn't see coming AT ALL: Jenny McCarthy and Jim Carrey have ended their five year relationship in which they have famously together raised (and supposedly "cured") Jenny McCarthy's autistic son. The news first broke via Jim Carrey's twitter, naturally.

Carrey posted on 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! ?;^>."

"I'm so grateful for the years Jim and I shared together," McCarthy, 37, tells Us in a statement. "I will continue to be in his daughter's life and will always keep Jim as a leading man in my heart." (Source)

I would love to know the juicy details of what went on here ... But maybe it's just a matter of two people growing apart into different people, realizing that they want different things, and at the end of the day their asses just don't have anything to talk about anymore. Such is life.
