Well things just escalated quickly.

Kid Cudi is the latest to add a chapter to the never-ending drama of loyalty and betrayal between him and Drake.

The rapper has publicly responded to Drake, who recently released a track with a lyric that many understood as trivializing Cudi's mental health issues.

"Say it to face, pussy," he tweeted. "You think it's a game. I wanna see you say it to my face. I'll be out soon. Promise."

Cudi — who is currently in rehab — also gave fans an update on his health status. "The love has been unfathomable. I look forward to hearing, breathing and feeling it all at ComplexCon Nov 5th. Love and back to rehab," he wrote.

Earlier this week, Drake allegedly responded to a fan on Instagram who expressed his frustrations with the controversial lines regarding Cudi.

"Mans need to stop mentioning my name when they get geeked. Supposed [to] be all love out here word to my bro Pablo," Drake commented, according to fan-captured screenshots.

And then on top of that, days after Drake released "Two Birds, One Stone," Cudi's manager Dennis Cummings turned to Twitter to blast the Toronto rapper. Cummings not only referred to Drake as "corny," but took the time to spill news that Drake had asked Cudi for a feature.

If all this beef is too much to keep up with, take a break and reminisce about the simpler days of 2009, when a young Drizzy made a cameo in the music video for Cudi's breakout hit "Pursuit of Happiness."
