Entourage star Kevin Dillon has landed the second lead in the new CBS pilot How to Be a Gentleman alongside David Hornsby.

The pilot, which is based off the book of the same name by John Bridges, centers on Allan, an uptight man (David Hornsby) who gets life lessons from his exuberant friend, Bert. Kevin Dillon will portray Bert, who has a youthful outlook on life, although he tends to overstep his boundaries.

David Hornsby wrote the pilot script. It is unclear when the pilot will go into production.

Kevin Dillon will next be seen playing Johnny Drama on the eighth and final season of Entourage, which will premiere sometime this summer on HBO.
