Best performance: Katy Perry

Best performance - Katy Perry?

However, as incredible as Rihanna was on stage, we do admire Katy for really singing her heart out with her hit E.T. followed up by new song Part Of Me. It appeared to be a bit of a dig at ex-husband Russell Brand, with powerful lyrics such as; "This is the part of me that you'll never gonna ever take away from me... I just wanna throw my phone away, find out who is really there for me".

We heart Katy's spirit - you can't keep her down! Plus she was rocking robot chic like we've never seen before.
