"After a great deal of care and consideration, I have made the difficult decision to file for divorce," Mellencamp, 43, wrote via Instagram on Saturday, November 2. "My priority is my children and ensuring that every care is taken with their privacy and wellbeing throughout this new chapter."

She added, "Making a public statement is not something I wanted to do, but in an effort to protect my family from undue speculation and rumors, I felt being open, honest and vulnerable was the best path forward."

Mellencamp and 47-year-old Arroyave, who has not yet publicly addressed the breakup, have been married since 2011. They share three children: Slate, Dove and Cruz. (Arroyave is also father to daughter Isabella from a previous relationship.)
