Entertainment Express: Jimmy Fallon, London Fashion Week, Pussy Riot, Ai Weiwei, Kelis

* It’s a new era for American TV as Jimmy Fallon officially took over the reigns of the Tonight Show last night – with the help of some of his friends – a little band called U2, performing on the Top of the Rock at with a glorious sunset backdrop, and that guy known as Will Smith, who helped him illustrate hip hop dancing.  Mariah Carey, Sarah Jessica Parker, Robert De Niro and even Joan Rivers, who had been banned from the show, dropped by.

* Amidst the relentless rain, London Fashion Week is trying to bring rays of sunshine to the UK. On Monday, Tom Ford showed off a playful side when he incorporated a football jersey a’la Jay-Z into his collection, while Vivienne Westwood used her show to urge against fracking.

* The two members of Pussy Riot, who had been in New York before heading to Sochi, have apparently been arrested in the Olympic city. It’s believed they were going to perform an anti-Putin song.

* A $1 million vase by Chinese artist Ai Weiwei has been destroyed in protest by a man in Florida, who says he was protesting a Miami gallery not showing local artists. The man, who faces criminal charges, claims he was following Weiwei’s own vase-breaking-protest. Of course, that was the artist breaking his own art – not something that didn’t belong to him.

* Kelis is about to release her new album, called Food – the title makes more sense with the news that she’s about to star in her own cooking show on the Food Network, from next week. Wonder if Milkshake(s) and Jerk Ribs will be on the menu?
