Taylor Swift Says She Had Backup Plan for Album Announcement at Grammys

Taylor Swift is pulling a Donna Kelce in the BS department -- telling her fans that she had a backup plan to announce her album if she didn't win at the Grammys ... OK, Tay Tay. 🙄

The singer relayed this sentiment to her Tokyo fans Wednesday night during performance #1 of her 4-show slate -- and yes, she claims she would've saved the news for Japan if things hadn't worked out for her at the award show this past weekend.

Taylor explains she'd only told a select few people about her album at that point -- including her producer, Jack Antonoff -- and then said ... "OK, if I’m lucky enough to get up there and win one thing tonight, I’m just gonna do it. I’m just gonna announce my new album."

She may well be telling the truth here ... but if we're being honest, it sounds like she's being a little insincere in the sense that she makes it seem like her winning at the Grammys wasn't a sure thing ... 'cause truth be told, it absolutely was, and T-Swift probably knew it.

In other words, Taylor is overplaying the modesty card -- which she actually channeled on Sunday night when she won Album of the Year for "Midnights" ... seemingly feigning surprise.

Anyway, TS continued to lay it on thick during Wednesday night's show ... telling the audience, "And luckily enough, that ended up happening ... thanks to you and your support, I was lucky enough to win a Grammy and tell you about it onstage at the Grammys. And now we can talk about it afterward, we can do like a debrief tonight."

Of course, her fans ate it up and cheered her on -- but again, this is very much so in the same vein as what Donna suggested just earlier in the day ... that she didn't know where she'd be sitting at the Super Bowl, and that she didn't think she'd be in a private suite.

BTW, Travis himself seems to be on this train too ... he made it seem like he didn't know what country Taylor was performing in ... before correctly saying it was in Tokyo.
