"Producers are dying to get her confirmed for the Charlie Sheen roast," a source close to the Comedy Central event (set to air September 19) tells the new issue of Us Weekly (out now). "It would be amazing television!"

Indeed: Richards, 40 -- who has daughters Sam, 7, and Lola, 6, with ex-husband Sheen, 45 -- has had a front row seat to his crazy antics sine they wed in 2002.

Adds the source, "She's interested. Denise has a terrific sense of humor."
