None of these celebrities having high IQs really surprised me. They're all either really thoughtful people or they succeeded in an Ivy League school, so it's not surprising they're intelligent. Ke$ha is the one kind of surprising one, but I seem to remember hearing that she's actually very thoughtful and only writes about partying because songs like that make her more money (citation needed, don't blindly believe this).
IQ scores are a general gauge of problem-solving, patience, and certain other cognitive functions, but there is no way to really gauge how "intelligent" someone is. What would that even mean? Someone can learn things really quickly and be good at problem solving, but never succeed in simple tasks that involve applying those thoughts to anything productive because of psychological issues. I know plenty of people who fit that description. Someone can conversely do very well in school and their job, solving problems but never really thinking past what they've been assigned to do. How can you really judge something that people don't even agree on in the first place? It depends on what you value.
By the way: IQ 140 here. As I said though, that doesn't mean much. I'm kind of curious to know other people on this forum's IQ scores if they're known, though. I feel INTPs would have naturally higher scores because of their obsession with patterns, not because they're necessarily more intelligent than other types.
