The couple - who have been dating for four years - believe their washing ritual has brought them closer together and they love having deep conversations when they bond in the bathroom.
Vanessa explained: "We shower, honestly, at least twice a day. We shower in the morning and we shower at some point during the day or before bed. It`s so funny because we`ve turned it into an intimate time for each other.
"We both have our own shower heads so we just talk while we`re soaping up and doing our hair. It`s not a sexual thing and it`s not a romantic thing, it just becomes an intimate thing.
"You`re in your full form, so to speak, and you`re vulnerable and we just both let our guard down. I`ve had some of my most intimate conversations with him in the shower."
Though Nick previously starred in his own reality show, -Newlyweds-, with former spouse Jessica Simpson, Vanessa insists she wouldn-t want to join forces with a partner for a programme of their own, though she won-t rule it out completely.
The -True Beauty- host told Parade.com: "I think that a competition reality show is different than a reality show. I personally have no desire. Nick has done one before and he was very successful at it and whatever he chooses to do with his future I will support him 100 per cent.
"Me personally, I don`t know. I think that there`s something to be said for keeping intimate moments to yourself, but he said it best, `You never can say never.` But I personally don`t want to do one."
