They met at the Rio Olympics and clearly hit it off, as evidenced by their Instagram dates (just pretend model Alessandra Ambrosio isn't there), and were supposedly spotted on a dinner date recently in New York.
While they haven't said anything publicly about being together, Lima did call Seacrest "charismatic-handsome" in an Instagram post, so clearly she's into him.
Good for them! How heart-warming and inspiring it is when two attractive people can get together like this.
Especially when one of them is a gorgeous Brazilian model and the other is the human version of a toothpaste commercial.
