Dmitry Lipkin and Colette Burson spent countless hours working side by side, painstakingly writing and developing HBO's hit TV show "Hung" ... so, naturally they're getting a divorce.
The couple co-created the show starring Thomas Jane ... about a well endowed high school basketball coach who becomes a male prostitute.
According to the docs, Dmitry filed ... citing irreconcilable differences ... after 8 years of marriage. He's requesting joint custody of their two kids -- a girl and boy, ages 11 and 7.
Schlong story short ... another Hollywood marriage bites the dust.
