Nick Lachey and Jessica Simpson, the first couple of reality TV, haven't talked in six years since their 2005 divorce.

During Bravo's "Watch What Happens Live" on Tuesday, Nick, 39, revealed that he has not spoken to his ex-wife in a while.

"It's been years [since I've talked to Jessica]. Years. Honestly, probably six years," Nick told host Andy Cohen. "It was like another lifetime ago."

Lachey and Simpson starred on "Newlyweds: Nick and Jessica," a three-season reality series that followed the couple as they worked on their new marriage. The couple divorced after three years.

During a question-and-answer game Cohen plays with celebrity guests calling "Plead the Fifth," Cohen brought up Simpson's father, Joe.

Cohen asked, "What is the best thing about no longer having Joe Simpson as a father-in-law?" 

Nick's brother, Drew, quickly interjected, "Everything!" 

" I don't have to play grab a-- under the table on Easter Sunday," Nick said with a laugh. 

"I am blushing!" Cohen responded. 

"Our publicist is freaking out right now," Drew, 36, said. 

In 2011, Lachey married Vanessa Minnillo. The couple had a son, Camden John, in September 2012.
