Lucille loves living a lavish lifestyle complete with extravagant condo, trips to the country club, and housekeepers to boss around.  Lucille is also a frequent alcoholic and loves destroying her childrens and grandchildrens' self esteeem, especially Lindsay and Maeby. 

During the season finale, it's revealed that Lucille was actually behind the illegal activities of the Bluth Company.
