Taylor Swift Will Perform Old Hits at AMAs, According to Oddsmakers

Taylor Swift is gonna tell Scooter Braun and Big Machine what's up ... by performing her old songs at the American Music Awards ... at least according to the oddsmakers.

The cyber-gambling site, SportsBetting.ag, is offering tons of prop bets on this Sunday's AMAs ... and bookies are banking on Taylor to sing the hits owned by BM, and for Swift to take home Artist of the Year over Ariana Grande.

The odds of Taylor singing stuff like "Shake It Off" are 1 to 5, meaning you gotta wager $500 to win $100. That's a pretty heavy favorite. The odds of Taylor eschewing songs from Big Machine are 3 to 1, meaning a $100 wager pays $300.

As you know ... there's some debate over Taylor's choice of songs for her big AMAs performance. She's angry at Scooter and BM over ownership of the masters from her first 6 albums. Taylor claimed BM was withholding permission for her to sing her old hits, but the label says she can perform anything she chooses during the live broadcast.

Of course, we've reported Taylor might not have enough time to rehearse her old songs. The jury is still out.

Taylor is the favorite to win Artist of the Year -- her odds are even -- while Ariana is second with 2 to 1 odds. Halsey comes in at 3 to 1, Post Malone is 7 to 2 and Drake is 4 to 1.

Taylor's also expected to go after Scooter and Big Machine during her acceptance speech for Artist of the Decade, and the odds of her saying "Big Machine" on the broadcast are 3 to 2, meaning a $200 wager pays $300.

Looks like Taylor's still making other people rich!!!
