The feisty tyke is back with a song whose video was the first by a British artist to reach No. 1 on the US’s Total Request Live. While on this side of the Atlantic, the climate’s changed considerably since she left (Amy Winehouse has become wiser, people have forgotten about chavs, Lily Allen’s stolen her schtick but wears pink dresses), her grime rapping is an anti-establishment, bold statement that puts her firmly on the musical map again. To quote the young lady, “I ain’t got the biggest breastesis/But I write all the bestest hits”.
