We've got the footage before it's aired on TV!
Okay, now that we've seen the final performance….
She's not 19 anymore. She's 29.
And not everyone is as athletic as Madonna!
The Britney that used to be able to dance fiercely is no longer. We're not exactly sure why she's gone, but - like we've said before - we'd love to find out!
If Spears gave an interviewing blaming her knee surgery and multiple knee injuries, then we'd understand why her movement has been impaired and our expectations would be different/lower. Or, there's also speculation that medication she may be on might be impeding her ability to dance.
It is what it is.
Thankfully, though, Britney is still Britney, bitch! And, we do LOVE this song! And we do love her!
Check out Spears performing Till The World Ends live for Good Morning America (above).
You will see this on TV Tuesday morning when the Brit GMA special airs.
P.S. Yeah, it sounds like she's lipsynching. We always expect her to mime, but we do always hold out the lingering hope that maybe she'll go back to live singing again some day!
