Taylor Swift will destroy Katy Perry’s Super Bowl halftime show

Katy Perry and Taylor Swift used to be quite good friends only a few short years ago. Then things got ugly when Katy apparently stole some of Taylor’s dancers for her tour, and then Taylor dissed Katy publicly about it and blah blah blah. Now, the feud continues, because apparently Taylor is planning to try anything she can to sabotage Katy’s upcoming performance at the Super Bowl halftime show this winter.

An entertainment insider tells RadarOnline.com exclusively that both singers have been using the same concert tour director and production designer, Baz Halpin, for years.

“Baz did Taylor’s most recent RED tour and the Speak Now tour, and he did California Dreamz and the current Prism tour for Katy,” notes the source.

And now that Perry, who will celebrate her 30th birthday on October 25, 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.”

The insider says that Halpin would “be nuts not do the gig” and there’s no way he’ll pass it up.

As for Perry’s thoughts on the subject? “Katy got word of Taylor’s ‘ultimatum’ and found it quite amusing.”

Oh, brother. I don’t know if any of this is true or why it even matters, but whatever. Taylor has got her own shit going on – 1989 is out and she’s headlining the New Years Rockin’ Eve celebrations here in NYC. Relax, everyone.
