The "SNL" star sat on top of the stage as his buddy performed at the Wolstein Center at Cleveland State University on Saturday night. He was spotted by several fans sitting on a platform for a few songs.
One fan tweeted, "One of the most beautiful things last night was seeing @machinegunkelly and @Petedavidson on the same stage together. They have a beautiful friendship and it made my heart happy!"
Another added, "Good seeing pete Davidson with a genuine good smile on his face tonight @machinegunkelly is the friend we all aspire to be #xxmas #idol #realfriend."
Just last week, Davidson scared his friends and fans with a social media post that led many to believe he was suicidal. He appeared on "Saturday Night Live" the next day, but only briefly.
MGK and Pete Davidson are close friends and the rapper rushed up to NYC to check on his pal.
