6. Marisa Tomei and Julianne Moore
This is another group of American celebrities that many people envy for their great friendship and the strong bold they have for each other.
Marisa Tomei and Julianne Moore attended the same university, Boston University, and somehow they fell deeply in love with each other.
That attraction has been there for almost a decade until when they discovered they were cousins. That explains why they had become good friends.
Although they looked somehow alike and were very good friends, they never thought they were cousins. And the discovery made them very happy.
These two American celebrities have acted in various movies and shows including “Crazy stupid love” which was released in 2011 and “My cousin Vinny”, among other great movies.
