#4 Rusev and Lana
The Ravishing Russian and The Bulgarian Brute were put together by the late great Dusty Rhodes as early as WWE developmental. Lana was introduced as Rusev's social ambassador and the duo had a great heel run as the anti-American, pro-Russian bad guys.

The two became good friends during this period. Their gimmick ended rather prematurely, even though Lana was hugely over with the fans at the time. As a result of this, both their careers floundered but the relationship sustained and they were dating soon enough in real life. Lana claims Vince McMahon was the only one unsure about whether to keep the duo as a package on the main roster.
Once news of their relationship became public knowledge, they were cast on to Total Divas. Their life leading up to their marriage was covered by the show.
