#8 Braun Strowman and Alexa Bliss
Like R-Truth and Carmella, Alexa Bliss and Braun Strowman were a pairing brought together for WWE Mixed Match Challenge. At the time, Bliss was the RAW Women's Champion.
Strowman is billed as being a massive six foot eight in height, and Bliss is just over five feet tall, making the size difference between the pair huge. The name for the couple was "Team Little Big", which seemed to suit them well. Team Little Big ended up doing well in the series, lasting until the semi-finals.
Through the series of WWE Mixed Match Challenge that they competed in, a more romantic aspect was hinted between them. This angle of their relationship has become part of a big storyline on SmackDown recently, with Alexa dressed as Sister Abigail appearing to Strowman during his Swamp Fight with Bray Wyatt.
This had continued on WWE TV, and the former Mixed Match challenge couple is now both entangled with The Fiend.
