2. Gabrielle Union and Dwayne Wade
Gabrielle Union was 42 when she married NBA star Dwayne Wade in 2014. At first she only saw Wade as a friend, and then he eventually became her best friend. After that, it just clicked that she was with who she was always meant to be with. 

"We were talking about something completely unrelated to us, and I looked at him and I just knew: I didn't want to be on this planet without him. I didn't want to not bear witness to him succeeding. I chose him," she wrote in her memoir, We're Going to Need More Wine.
