Q: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Passage: Zandalee Martin is a young boutique store owner living in New Orleans who is sexually frustrated and feeling unfulfilled with her marriage to Thierry Martin, and eventually gets tangled in a passionate, sensual and torrid iadulterous affair with her husband's mysterious and free spirited old friend Johnny Collins. Zandalee and Thierry's marriage has hit a snag and seems to be eroding due to his lack of passion. 
Zan needs to explore, while Thierry wants to withdraw, and has become more and more distant and impotent in their relationship. He used to be a poet, but now has taken over the family's communications business after the death of his father. As time goes on, Thierry has to sell the business and become basically a (vice president) figurehead. He is emotionally adrift as his dreams give way to disillusionment.
Johnny, an artist painter by trade, has been working for Thierry's business to help support his paintings. His only religion is self-gratification. Johnny also sells and mules cocaine for a local drug dealer as another source of income for himself. Having not seen each other in a while, the two run into each other at a bachelor's party. After the party, Thierry brings Johnny home to meet Zandalee and his grandmother Tatta. While talking about old times, Johnny offers to paint a portrait of Thierry at their home.
A:
What does Johnny's affair partner do for a living?
