This is total news to me, but apparently Walk the Line star Joaquin Phoenix has retired from acting to pursue a career in rapping, with an album to be produced by Sean Combs. He is scheduled to make his first public performance Friday at a Las Vegas club.

At the same time, Casey Affleck has decided to direct a documentary about Joaquin’s journey into the music business. Not only are Casey and Joaquin friends, but Casey is married to Joaquin’s sister, Summer Phoenix.

And I, for one, am now actually in Phoenix, and it is not summer, and I was just wearing a flimsy spaghetti-strap tank top at 11:30 pm and I was just fine. I don’t even want to think about how awful it’s going to be trying to run a half-marathon in the middle of the day, which is what I am supposed to do on Sunday. It’s a completely insane idea — but still seems more sensible than Joaquin Phoenix as a rapper.

Casey and his wife, Summer Phoenix, welcomed their second child on Saturday.

Babies. So hot right now.
