Season and place: Season eight, second place
Both of Adam Lambert's albums, the Grammy-nominated For Your Entertainment and Trespassing, made it into the Top 10 of the Billboard 200, with the latter reaching the No. 1 spot. He has guest-starred on several TV shows, including Glee, and is known for publicly advocating for LGBT rights. Even if his net worth wasn't $12 million (it is), he'd still make our list for being a very influential social activist. His next album, The Original High, will be released on June 12, and his new single, "Ghost Town," is out now. You go, boy.
