The country singer took to social media to clear the air over the tweets, which were made from 2009 to 2011, and to assure fans that he was deeply sorry for offending anyone.
"Everyone knows comedy has been a major part of my career and it's always been out there for everyone to see. That said, anyone who knows me also knows I have no tolerance for hate of any kind or form."
Shelton added, "Can my humor be inappropriate and immature? Yes. Hateful? Never. That said I deeply apologize to anyone who may be offended."
The Twitter handle @MusicFactsTea was the first account to resurface the old tweets, which caused a frenzy on the social media platform.
After the old messages—which have not been directly confirmed by Blake—went viral, the hashtag #BlakeSheltonIsOverParty began to pick up steam.
After fans from far and wide criticized the post, the daytime talk show host tweeted: "I'm highly aware of the racism that exists in our country. It is the farthest thing from who I am."
