There has been some speculation over the past few weeks about Zelina Vega after her alliance with her husband, Aleister Black.Her name change was confirmed this week on WWE SmackDown when she headed to the ring alongside her husband, and it was revealed on-screen that she had lost her last name. Moving forward, it appears that she will only be known as Zelina, which could be down to her partnership.You can see WWE confirming her name as just Zelina at the end of this video:Given that the WWE Universe knows she is now working with her husband, it makes little sense for her to use a different surname. It appears that WWE could have decided it was better to take Vega away than change her name to Zelina Black.That being said, it seems that she is already paying her dues as part of her alliance with her husband, since they have now targeted the World Champion.Zelina Vega slapped WWE Champion Cody RhodesDuring this week's episode of SmackDown, Cody Rhodes announced he was moving on from Drew McIntyre, and a new challenger then presented himself.Aleister Black and his wife made their way to the ring, and it was Zelina Vega who then slapped him across the face and made their target clear. The main event will now see Black take on Rhodes, and it will be interesting to see if Damian Priest rears his head again, after weeks of issues with Black.Rhodes does need a new challenger, and if he is to step into a long-term story with Black and Zelina, then he could need a female to help overcome the numbers game. While the WWE Universe will push for Brandi Rhodes, it's worth noting that she recently welcomed her second daughter, so it's unlikely that she will be able to return to help her husband this time.
