Girls are going mad for Harry Styles

One Direction have been a huge hit in the US – especially curly-haired Harry Styles.

The 18-year-old heartthrob, who celebrated his birthday on Wednesday, has already built up an army of American admirers – including students from UCLA.

‘We were bombarded with young women coming into the hotel to drop off gifts for Harry,’ a hotel worker tells the Daily Star.

‘We’ve had hair products and DVDs, but most of it was underwear, in Victoria’s Secret bags.’

On top of the love for Harry across the pond, he also had a pile of goodies to come home to when he arrived back in the UK yesterday.

‘Thank you all on behalf of @Harry_Styles for the cards (124 at last count!) letters & gifts with lovely birthday wishes,’ Tweets Harry‘s mum Anne Cox.
