"Just spit balling here...I'm trying to help...you know what f**k it...you will be fine....I hope...God Bless...K Hart Out," he ended his text to Schumer.
As everyone does with a funny text convo, Schumer took a screenshot of the text and shared it on Twitter with the caption, "Hostile text."
After she informed the Get Hard star that she would be sharing the conversation, he added, "I'm just trying to be F—KING SUPPORTIVE... is this Miley Cyrus?... Wait this is the wrong host... this message was for Miley."
When sharing that NSFW tweet, Schumer had to add, "He was messing with me. We are friends. Boooo." Apparently some people didn't realize that the two were just kidding around! Hart, 36, hosted SNL last season on Jan. 17, so all jokes aside, he probably is a really good person to get advice from! As for that mention of Cyrus' name? She hosted the show season 41 premiere of the SNL last week. The Trainwreck star is clearly excited to host SNL for the first time. Earlier on Saturday, she shared a baby photo of herself on Twitter. "Excuse me, Mom and Dad, I am hosting Saturday Night Live tonight," she captioned the cute pic.

After winning an Emmy for Best Variety Series for Inside Amy Schumer last month, ET caught up with the comedian backstage, who revealed that her pal Jennifer Lawrence had messaged her during the show. "Jennifer sent me a really sweet text," Schumer shared. "She said that I looked pretty but not smart." Schumer totally owned the Emmys with another funny lady, Amy Poehler. See their epic on-stage moment in the video below.
