Dissing Nickelback has become a time-honored tradition. But when former California Governor and New Celebrity Apprentice host Arnold Schwarzenegger took a swing at the band on Valentine's Day, comparing the Canadian rockers to the very unpopular U.S. Congress (and herpes), they were not having it.

The group, who are working on a new album, responded that they were big fans, then snapped back with a mention of Ahnuld's disastrous turn as Mr. Freeze in 1997's reviled Batman & Robin movie.

.@Schwarzenegger big fans. Approval rate this: Batman & Robin. Please leave us out of your future wisdom drops. Danke Shön Herr Governator. — Nickelback (@Nickelback) February 14, 2017

The Governator got it, appreciating the "ice cold" burn and asking them if we could all just agree that gerrymandering is bad -- perhaps not realizing that as Canadians they don't really have a horse in this race. That seemed to settle the mini-beef, with the 'Back responding "#Respect."

You might recall that the Arnold mini-feud was preceded by a slag from Facebook founder Mark Zuckerberg and a Canadian cop in December, and then, just a few weeks ago, another diss-fest launched by The Chainsmokers, who took a whack at the 'Back, and, of course, they hit back.

.@TheChainsmokers you may find this hard to believe, but we've been called way worse. It's only music guys, keep up the great work. #Truth pic.twitter.com/HnTpkELZha — Nickelback (@Nickelback) February 2, 2017

In the meantime, Nickelback recently signed a global record deal with BMG, and earlier this month they announced the June 9 release of their upcoming ninth album, Feed the Machine, preceded by its eponymous first single. They will be joined in the tour by Shaman's Harvest, Daughtry and Cheap Trick, on the summer trek that kicks off on June 23 in Noblesville, Indiana.
