The former 98 Degrees singer no longer talks to his former flame following their split in 2005, reported Radar online.
When asked if he is still on speaking terms with Jessica - who is mother to Maxwell, two, and 16-month-old Ace with her former NFL player husband Eric Johnson, whom she married in July 2014 - Nick said, "No, no. We don't stay in contact at all."
Shortly after their wedding, Nick and Jessica starred in the MTV show 'Newlyweds: Nick and Jessica' which documented their life as a newly married couple.
"I would never do the kind of show like I had done previously," he said.
