A famous person I take a lot of interested in is Oprah Winfrey.
Doesn't it have to be like this? "the" should come as it's a specific person and "interested" seems to be grammatically wrong.
The famous person I take a lot of interest in is Oprah Winfrey.
The first sentence is correct if you change interested to interest. It's better with the indefinite article a.
