Get the latest on the stars' Twitter feud

Twitter feud alert!

Seth Rogen had something not so nice to say to Nancy Grace earlier today after she went on an anti-marijuana Twitter rant.

Grace took to the social media site to share her thoughts about a recent Colorado shooting, writing, "Cops say daddy eats marijuana & goes crazy. He shoots his wife in the head while she pleads with 9-1-1 for help! #PotToBlame?"

"If pot makes you mellow and laid back, why does this guy allegedly turn berserk and gun down his wife? #PotToBlame?" the 54-year-old HLN host continued.

.@NancyGraceHLN you are a fucking dumbass.

She added, "How many people must die before this stops?! #PotToBlame?"

That's when Rogen, an outspoken marijuana advocate, fired off. "@NancyGraceHLN you are a f--king dumbass," the Pineapple Express tweeted.

And believe it or not, Grace responded! "@Sethrogen hi seth! thx for watching!" she posted on her Twiiter.
