Tara/Victoria has gone by either name whether you've followed her on WWE or TNA. Rebranding is important. That's something you can only do in the entertainment world. It's not like I can work at Google then leave to work at Amazon and say, "you can call me Tony now." It would be weird. What's even weirder is the thought that I could even get a job at Google or Amazon.
The person who got Tara into wrestling is a wrestling legend herself: Chyna. It's reported that Chyna told Tara that she should do wrestling and the rest is history. I love that someone's life could just do such a direction change. Just deciding to do wrestling as a career seems like a pretty huge decision. Not everyone is cut out for body slams and submissions.
