Meghan Trainor may be channeling Britney of late, but it’s the Backstreet Boys that will forever have her ’90s-kid heart. That’s the only plausible explanation for the outpouring of saccharine that occurred on ABC Thursday night, where Trainor sang “I Want It That Way” with the not-a-boy-well-into-being-a-man band on an episode of Greatest Hits. Trainor even did the boy-band shuffle and got serenaded by her one true love, Brian Littrell. There are a few flubs and a heavy dose of cheese in the performance, but the wish-fulfillment factor makes it a little more than a mistake. Take a deep dive into the bucket of corn syrup above.
