Chris Rock recommended his ex-wife's divorce lawyer to John Mulaney

Chris Rock opened for John Mulaney's new From Scratch set last week, and he revealed how he's actually helping the 38-year-old comedian start over while visiting The Tonight Show Starring Jimmy Fallon.

"Mulaney's working on new stuff," Rock said, after also just casually mentioning he did a show with Dave Chapelle and Trevor Noah the night before (What?!). "Mulaney's getting divorced. This is how much money I lost in my divorce: I recommended my ex-wife's divorce lawyer."

It's natural instinct to assume Rock is doing a bit, and he knew that: "You think I'm joking. I really did." (He still may very well be joking.)

Mulaney returned to the stage for the first time since completing a 60-day rehab stint to address alcoholism and cocaine abuse. The set, held at New York City's City Winery from May 10-14, almost immediately sold out. 

May 10, news broke that Mulaney had asked for a divorce from his wife of nearly seven years, Anna Marie Tendler, three months ago. Three days later, internet gossip circles were rocked even more when People reported that Mulaney is dating actress Olivia Munn.

Rock, meanwhile, finalized his divorce from Malaak Compton Rock in 2016—after announcing the end of their 19-year marriage in 2014.
