We didn't see this feud coming.

Tom Hanks' son, rapper Chet Haze, is using his Twitter to launch an outright attack on Howard Stern and his crew after they made some not-so-nice, NSFW comments about the 24-year-old Hollywood heir on Stern's Sirius radio show. Earlier this month, Chet's name came up when fellow radio personality Rude Jude stopped by the show. "I feel bad for Tom Hanks," Stern joked. "My white son has homies."

This wouldn't be the first time Stern, 61, has insulted Chet. Upon learning of his rap career in Feb. 2011, he joked, "Where'd he grow up, Beverly Hills?"

"Listening to the @HowardStern show this s--t isn't funny at all... Lame yuppie humor #StepYourGameUp #Outdated," he tweeted in response to Stern's recent quips.

That message then led to a barrage of tweets from Chet, whose legal name is Chester Hanks, that were all later deleted but tracked by numerous media sites. "Let me come up on your show bitch," he wrote. "Come catch this fade ... have me live on the air and we can go pound for pound see who looks like the fool... easy to talk s--t in a closed off room... have me up there in the studio with you let's give the [people] what they want."

The tweets went on to become more threatening. "Do you have any idea how badly I am going to assault you when I see you… You can't run from me forever knock knees… Listen. One day, maybe tomorrow, maybe 10 years from now, I am going to see you in person, and I am going to hurt you," he wrote. "I hope you travel with security!!! PLEASE have me on the show… it’s a shame you don’t hang in the same circles as my family (not enough bread for that) cuz if you did I woulda already seen u."

Later realizing that this might not be the best publicity move, Chet acknowledged that his outburst would make headlines -- but in the most profanity-laden way possible. "I AM A WALKING PR DISASTER AND I COULD LITERALLY GIVE A F--K LESS!!!!!" he wrote. "OH WAIT I MEANT I LITERALLY (sic) DON'T GIVE A SINGLE F--K!!!!"
