Cudi revealed on Facebook late Tuesday that he had gone to rehab on Monday, after grappling with anxiety and depression throughout his life.

Cudi sparked a rap flap in September when he took to Twitter to call out rappers he claimed had others write their songs for them… like Kanye West and Drake.

“My tweets apply to who they apply. Ye, Drake, whoever,” Cudi wrote, along with some profanity.

West, who signed Kid Cudi to his G.O.O.D. Music label in 2008, responded while performing on stage during a Tampa, Florida, concert stop.

He paused his performance of the song “I Don’t Like” to tell Kid Cudi “Don’t never mention ‘Ye name. I birthed you.”

Cudi’s debut single after joining West’s music label, “Day ‘N’ Nite,” hit No. 3 on Billboard’s Hot 100 in May 2009.

Looking ahead. Cudi, who won a Grammy in 2011 for Best Rap/Sung Collaboration for the song “All of the Lights” – along with Kanye West, Rihanna and Fergie – promised that his latest album is still on the way and that he planned to attend ComplexCon, a convention billed as “This generation’s World Fair,” scheduled for November 5-6 in Long Beach, California.
