Kid Cudi is in rehab for depression and suicidal thoughts.
Before he checked himself in, he lashed out at Drake and Kanye West, calling them "fake."
Drake just struck back at Cudi in his track 'Two Birds, One Stone.'
However, 'Ye has already forgiven him.
In Los Angeles last night Kanye paid tribute to Cudi by getting the fans at The Forum to sing Cudi's hook from 'Father Stretch My Hands Pt. 1.'

"Let's sing this one time for Cudi," 'Ye said. "So Cudi, he in rehab right now, but he got a number one song on the radio, and I want you to sing so he can hear it."
