The couple married in 2010 in an intimate ceremony in New Mexico with Ally’s son Liam in attendance.
Ally adopted Liam in January 2001, with Harrison also adopting him in 2009, after dating Calista for seven years.
He later spoke about how Liam always was part of the duo’s relationship.
“I think Liam was about 6 or 8 months old when I met him and Calista,” he told Parade in January 2010.
“We have been together ever since … I wasn’t expecting it at all. The unexpected part was certainly true. And the joy part is also true.”
