Joaquin Phoenix, whom we can no longer look at without thinking of Johnny Cash, used a Paul Newman benefit to announce his retirement from acting. As you do.

I want to take this opportunity … to give you the exclusive and just talk a little bit about the fact that this will be my last performance as an actor. I'm not doing films anymore. … I'm working on my music. I'm done. I've been through that.

We have a feeling this "retirement" is going to stick the same way it did for Brett Favre and Michael Jordan.

Eddie Murphy, on his plans to retire just a few years too late:

I have close to fifty movies and it's like, why am I in the movies? I've done that part now. I'll go back to the stage and do standup.

Jennifer Lopez has told the February issue of Harper's Bazaar that she is considering retirement upon the birth of her twins:

Post birth, Lopez is still unsure of whether she’ll be a working mom.

"I don’t know — and I like that, because my life has been so planned for so many years," she reveals. "Once I did the tour, I really just wanted to shut it down."

Do it, Jennifer! We implore you to stop making music! But, uh, y'know, just for the sake of those kids.
