Twitter user @mileyfan2014 even posted a side-by-side comparison image with the caption: "I might be reading to much into this #HalftimeShowKatyPerry."
According to a report by TMZ in September, the bad blood began when three of Taylor's dancers quit to go work for Katy.
Taylor "felt betrayed" because she had considered the dancers as family, the news site reported.
Much has been made about the feud between the pop singers as Katy recently addressed it in the February 7 issue of Billboard magazine.
She told the weekly: "If somebody is trying to defame my character, you're going to hear about it."
Fans began to speculate about a rivalry in September when Taylor said in a Rolling Stone interview that her song Bad Blood was about a female musician - and "straight-up enemy."
Katy then tweeted with a possible slant in Swift's direction: "Watch out for the Regina George in sheep's clothing."

The pop stars have been in each other's paths for many years, and the pair even seemed to be friends for a while, gladly posing for photos together.
Perry could be be the star Swift was referring to as the Shake It Off hitmaker told Rolling Stone: "For years, I was never sure if we were friends or not.
"She would come up to me at awards shows and say something and walk away, and I would think, 'Are we friends, or did she just give me the harshest insult of my life?'

"Then last year, the other star crossed a line. She did something so horrible, I was like, 'Oh, we're just straight-up enemies.' And it wasn't even about a guy!
"It had to do with business. She basically tried to sabotage an entire arena tour. She tried to hire a bunch of people out from under me."
