Did you hear? America's favorite boobs—those belonging to Katy Perry—are performing at the Super Bowl XLVIV Halftime Show. Did you also hear? Taylor Swift, b. 1989, hates those boobs. So naturally, Radar reports, Tayla is gonna destroy the halftime show.

According to Radar, Swift has issued an "ultimatum" to concert tour director and production designer Baz Halpin, who's been employed by both Swift and Perry in the past. Halpin absolutely cannot produce Perry's halftime show, or else:

Now that Perry ... has scored the high-profile Super Bowl XLVIV Halftime Show, she's asked Halpin to design it. "He's working out the money details right now, but it's obviously a huge career highlight for him and he wouldn't pass up the chance to do it," says the insider.

That dedication to Perry isn't exactly sitting well with 24-year-old Taylor. "She got word of Baz agreeing to do the show for Katy and Taylor's flat out said she will not hire him ever again for any performance or tour if he goes ahead with his decision."

Katy reportedly found the ultimatum "quite amusing."

It was announced today that Taylor will headline New Year's Rockin' Eve 2014, which is almost as good as the Super Bowl halftime show.
