There's little worse than introducing yourself to someone only to be told you've already met, so we're cringing for Britney Spears today after she claimed she has never met Taylor Swift despite the existence of photographic evidence to the contrary.

While being interviewed on the Kyle and Jackie O radio show on Monday, the 34-year-old singer was asked which solo star she would rather fly long-haul with.

"Who would you rather sit next to on a 24-hour flight to Sydney: Taylor Swift or Katy Perry?" the host asked the Toxic singer.

Playing the diplomat, Britney responded: "I don't know. That's hard, They're both so cool. I don't know."

Not content to leave it there, the radio presenters probed a little further, asking: "Do you know or do you have a friendship with either of them?"

And that's when it all got a little stressful for Tay-Swizzle fans.

After confirming she had indeed met Katy Perry – albeit briefly – Britney insisted that she and the Blank Space singer had yet to cross paths.

"I briefly met Katy Perry at the Smurfs movie premiere in 2013 and I met her there really quick," Britney explained. "So maybe because I've met Katy Perry, I would say Taylor Swift because I've never met her before."

Cue the exploding of heads in the T-Swizzle fanbase.

Stunned that the pop icon would forget meeting their idol, Tay's fans trawled the internet and unearthed not one but two snaps of Britney happily posing alongside Tom Hiddleston's new bae.

Turns out Brit and Tay met as far back as 2003 before cosying up for yet another snap in 2008…
