Music Mogul -- Which Marriage Were You In?

The ex of Jimmy Iovine may have thought she was the one doing the dumping when she filed for divorce last week, but apparently Jimmy checked out of the marriage long before she did.

According to Jimmy's response filed yesterday, the couple separated on January 15. But Vicky Iovine is under the impression the marriage ended a month later on February 15.
