#3 Former WWE Superstar Summer Rae
After spending some time in WWE's developmental territory, Summer Rae was moved up to the main roster, where she was introduced as Fandango's dance partner. Rae was let go by WWE in 2017, after being inactive for around a year. Recently, WWE started airing vignettes hyping up the arrival of a mystery woman, and Rae decided to have some fun on social media. Around the same time, she posted a tweet in which she hinted at a WWE return, and fans speculated that she was the mystery woman. The tweet was posted less than 24 hours after an episode of SmackDown came to an end, which featured the vignette.
This was all for naught though, as the mystery woman was later revealed to be WWE Superstar Carmella, who had been repackaged after a brief period of inactivity on WWE TV. Carmella is a former SmackDown Women's Champion and has also won the women's Money in the Bank briefcase on one occasion. At 32, Carmella still has a lot left in the tank in regards to a WWE run. As for Summer Rae, there's no indication that we will get to see her in a WWE ring in the future.
