Her best performance of Firework (for me)!

Performance - Great
Singin - Could have been better..

Thank you.

I've been waiting for this all day. Do you happen to have other performances

Yes, they're on BBC's official website, but they're not available outside UK , hopefully the person who uploaded them will upload more

Loves it

A great performance, and she's gorgeous.

I think there is room for her to improve her live vocals, though

I hate this, just like the VEVO thing

She slayed. Fu*king amazing. EPIC

The vocals were not that great but the performance was good. Amazing crowd.

Thtat crowd is really amazing.
I wish i were there.
And Katy slayed the perfromance

Those vocals. OMG.

She killed it and she looked amazing!

Great crowd! The First "You just gotta... like the fourth of july" were kinda shaky but I LOVED IT!!!

She did amazing

but why she keep trying to change her voice in the first verse?

I don't think she was trying

I'm actually not a pressed hater. I love Katy. Firework is one of my most-played songs of the last few months. But gurl come on. Those vocals were just sad.

ok
