Drew Barrymore is looking forward to "ever after." The actress, 25, and her boyfriend, outrageous comic Tom Green, 28, are planning to get married, her publicist announced yesterday. No wedding date has been set. This will be the second marriage for Barrymore, who recently wrapped the movie version of "Charlie's Angels," costarring Cameron Diaz, Lucy Liu -- and Green, who has a cameo role. He's best known for his MTV show, though his movie, ", Road Trip," was something of a hit earlier this summer. (He also recently went public with his battle with testicular cancer, documenting his surgery in a TV special.) Barrymore, who had been briefly engaged to actor James Walters in 1992, married Los Angeles bar owner Jeremy Thomas in 1994. The union lasted 11 months. Green has never been married.
