The Jonas Brothers member and his wife Danielle star in the new E! series Married with Jonas, which debuts on Sunday (August 19) at 10pm.
The couple opened up to Access Hollywood about their relationship and how the show has impacted on their lives.
"Our communication levels have gone through the roof," Jonas said.
He went on to say that he received advice from fellow E! star Giuliana Rancic.
"Giuliana Rancic said to us early on, 'Learn to talk to each other through this because if you don't, it will destroy you, but it could actually help,' and it really has," he continued.
Meanwhile, Danielle spoke about her desire to start a family, saying: "I can't wait, I can't wait to be a mum."
Jonas previously said that filming the reality show has helped his marriage.
