Lily Allen shows no Fear as she goes sledging in the snow

With her single at No.1 and snow deluging London, Lily Allen was feeling particularly playful this morning.

The singer, who hit the top of the charts with The Fear last night, joined the many thousands making the most of the weather.

Unlike many of those enjoying a day off school and work, however, she had already put in a shift, appearing on GMTV and This Morning.

But then the 22-year-old was off to a park near her north London home, where she enjoyed sliding down the hill on a makeshift sledge.

After finding a temporary roadsign near some roadworks, Lily turned the sign into a sledge and screamed in delight as she whizzed along the snow with a male friend.

She was joined by hundreds of locals, mostly families, who had also come armed with tea trays and plastic bags to try their hand at sledging.

Wearing her controversial Prada Finnish fox fur hat, Lily was wrapped up warm in a chunky black coat, denim hotpants, black tights and Ugg boots.

As well as sledging and indulging in snowball fights, the Smile singer also built a snowman.

Earlier today, Lily kickstarted her snowy fun by throwing snowballs at photographers outside the ITV Studios on London's South Bank.

After previously claiming she was more mature than her friends the same age, the 22-year-old singer reverted to her youth as she enjoyed snow games.

She said recently: 'My mates are in a totally different place. I’ve grown up so much and they are still all into going out and dancing and taking drugs. I hang out with much older people.

'I’m meeting more interesting people who tax my brain.'

But clearly today Lily was more interested in some good old-fashioned fun rather than having her brain 'taxed'.

Appearing on GMTV this morning, Lily complained she had to go on TV without her hair being styled after the programme's hairdresser couldn't get to the studios because of the adverse weather conditions.

Along with the rest of the GMTV presenters, Lily had to do her own hair and make-up before going on air.

She told host Ben Shepherd: 'No one turned up because of the snow so I've had to do it myself and I've got this greasy fringe - it's disgusting.'

Lily was clearly in good spirits after her song The Fear hit number one and her second album It's Not You, It's Me was received well by critics.

She enthused: 'It feels brilliant, I'm very happy - I'm just over the moon.

'I didn't really know whether I was capable of doing it all over again. It's a good bit of affirmation for me.'
