JESSIE J made a cracking entrance by exploding out of a giant safe on stage.

She then nearly lifted the roof off the Odyssey Arena with her song Price Tag.

Looking purr-fect in a slinky leopard print dress last night, Jessie also presented a touching video tribute to the late Amy Winehouse put together by fans.

The feisty star told me before her performance that she wants Coldplay crooner Chris Martin working with her on new show The Voice.

They were on the EMA bill too and she vowed to hunt him down and get him on her team for the talent show.

Jessie, 23, told me: “I’ll say to him, ‘Chris Martin. Be part of The Voice UK with me. If you’re not going be on the panel, come and be on my team. Let’s go.’ He’ll probably say no, though.

The singer is so far the only confirmed member of the BBC1 show’s coaches panel.

They’ll mentor contestants who audition “blind” so they are judged on their voices alone.

She added: “I also want Lenny Kravitz to join the panel because he is just so fit.

Well, a girl has needs, you know...
