lol it's always so hilarious when people try to knock the US talent and put UK acts above them. The UK used to have alot of credible artist but that was back in the stones ages with the Beatles, George Michael, U2 (who are Irish) etc.
As of right now, Adele and Jessie J and a couple others are the only ones waving the fag of talent and when it comes to Adele she's just the flavor of the month. She'll fade away after this album just like Duffy, Amy, James Blunt, Spice Girls and all the other British acts who world salivates over for whenever America decides to pay attention to them.
Like someone said above, talent is relative but everyone damn well knows some of the greatest singers/performers in Music are from the US.

With regards to this perofrmance, *facepalm* The only thing more overrated than her is the group she came from. 5 of the most average/boring women put in a group. Her and Nadine have decent voices tho.
She's supposed to be PERFORMING here and yes, that includes some dancing.
She may be shy or whatever but anyone could've done this performance.
