For someone who's happily married and has a child, Nick Lachey sure spends a lot of time focusing on his exes.

After accusing Kim Kardashian of using their former relationship for publicity, he's now directing his venom at Jessica Simpson and her family. While chatting with Andy Cohen on Watch What Happens Live, he made a concerted effort to fan the gay rumors against Jessica's famous dad, Joe Simpson, that we had just about forgotten.

During the show's "Plead the Fifth" segment, Andy asked him what the best part about not having Joe as a father-in-law. Nick responded by telling him that, “I don’t have to play grab-ass under the table on Easter Sunday.”

You'll recall that Joe and wife Tina announced last November that they were splitting after 34 years of marriage, and rumors surfaced that Joe had come out as gay to his family. The allegations were quickly shot down by a family rep, who declared, "It's an amicable split and there is no third party involved. Any other related allegations are completely false." But many other sources claim the rumors are, indeed, true. Nick Lachey seems to believe them, anyway...

On the Bravo show, Nick also revealed that he hasn't spoken to Jessica in six years and that it feels like his marriage was "another lifetime ago." It also goes without saying he wasn't watched an episode of their former reality show Newlyweds during that time either.

"As you can imagine, that's not popular viewing in my house. We don't sit around as a family and watch the old DVDs," Nick said with a laugh.

Nick and Jessica divorced in 2005 after three years of marriage. Since then, Jessica has gone on to create a billion dollar empire with her Jessica Simpson Collection clothing line. As for Nick... let's just say he's not raking in that kind of dough.

Do you think Nick was out of line in this interview?
