Jessie J performing 'Who's Laughing Now' at Royal Albert Hall

[khakuda]

Can totally sympathize having played in bands over the years. Sometimes all you can hear is drums or someone else's instrument. She's so darn great, who cares.

If you watch other videos she talks about how she can't hear the monitors!

[wushish]

Wow Jessie J singing out of tune, something i'd never thought i'd live to hear. Nevertheless she has a perfectly reasonable excuse, still a proud heartbeat

[wushish]

@8374472 Very true ha. You forgot to mention not singing at all [erhem britney spears]

[mikeryan2000]

Love her to death but something's happening here. She started in the wrong key right off and so she's off for the majority of the song :/

@mikeryan2000 she was having trouble with her 'in ears' if u watch nobody's perfect u will see her getting frustrated with the sound guy!!
