Los Angeles: Singer Nick Lachey says he is not "in contact at all" with his former wife Jessica Simpson.
Lachey dated Simpson for five years before they split in 2005, reports femalefirst.co.uk.
"No, no. We don't stay in contact at all," he said when asked if he still speaks to Simpson.
Simpson is mother to Maxwell, two, and 16-month-old Ace with her husband Eric Johnson, whom she married in July 2014.
She had starred in the MTV show "Newlyweds: Nick and Jessica" with Lachey shartly after their wedding.
However, Lachey, 41, has ruled out the possibility of returning to reality television with his wife Vanessa Minnillo, 34, who is expecting a baby girl, and their two-year-old son Camden.
"I would never do the kind of show (like) I had done previously," he said.
