Harry Styles on the tube

One Direction star Harry Styles took a tube train to Sir Elton John's London concert last night (12.09.13).

The 19-year-old pop heartthrob joined passengers on the Northern Line branch of the London Underground to get to The Roundhouse venue in Camden where a 5,000 strong crowd filled the venue to watch Elton perform as part of the iTunes festival.

Harry even got a shout out from the music legend who shouted out: "Thanks to the fabulous Harry Styles!"

This was met with boos from Elton fans which the 66-year-old musician responded to by declaring his love for 1D - which also includes Zayn Malik, Louis Tomlinson, Niall Horan and Liam Payne.

He yelled: "I love One Direction, f**k off."

Elton - who has two sons with his husband

David Furnish - then added: "And of course, my angel David."

Harry was delighted to have the honour of meeting Elton after the show and took to his Twitter account, to say: "@eltonjohndotcom is a living legend."

The star-studded crowd also included 'Star Trek Into Darkness' star Benedict Cumberbatch, Stephen Fry and Tom Odell.
