The 2012 Academy of Country Music Awards kicked off in typical fashion, with veteran co-hosts Blake Shelton and Reba McEntire trading barbs about current events and their fellow country superstars. However, one joke involving a well-known bit of gossip seemed to genuinely stun one of the superstars in the audience--namely, Taylor Swift.

Shelton and McEntire, while cracking a few jokes about current NFL darling Tim Tebow, made reference to the rumor that the uber-famous quarterback had gone on a date with Swift--a report that made headlines all over at the end of February. "Now we know what he's been praying for," Shelton deadpanned.

When the camera flashed on Swift, the blond singer had a baffled look on her face. Now, we know Swift is notorious for her dramatic on-air reactions, but in this case it appeared to be the real thing.

The incident sparked some chatter on Twitter, with viewers mostly chuckling about the joke. "Taylor Swift was looking extra salty after that Tim Tebow joke, HA!" one fan tweeted, while another enthused, "Oh T-Swift you're just too cute. And you so just confirmed that date with Tebow."

Other fans felt Shelton went too far: "He was making fun of Tim Tebow and Taylor swift," read a disgruntled tweet. "It was just rude."Taylor Swift--"What you talkin' about, Blake?"

Swift is up for several awards at the ACMs, including the coveted entertainer and female artist of the year categories. Early winners included Miranda Lambert for album of the year, Lady Antebellum for group of the year, Toby Keith for video of the year, Jason Aldean for vocal event and single of the year, and Thompson Square for duo of the year.
