Well, another celebrity couple is calling it splitsville and I'm actually a little shocked about this one!

I thought Ashlee Simpson-Wentz and Pete Wentz were in it for the long haul but I guess she's following in her sister's footsteps. Ashlee filed for divorce citing "irreconcilable differences."

Here's the couple's statement:

"After careful consideration, we have made the difficult decision to file for divorce," the couple said in a joint statement, released by a spokesperon, to Access. "We remain friends and deeply committed and loving parents to our son Bronx, whose happiness and well-being remains our number one priority. We ask that everyone honor our privacy as we navigate this next phase of our lives."

So to honor their request for privacy *wink wink* and to find out the terms of custody & child support (very interesting!), go to Yahoo!.
