Rihanna travels in style to her arena show... as she rides the tube with her fans! ~ dailyceleb

She is a millionairess at the tender age of 23. But popstar Rihanna is clearly not your average spoilt celebrity.

Clearly keen to experience all the highs - and lows of London - the bold singer took to the London Underground to travel along with her fans to her concert at the O2 Arena.

Superstar crush hour: Rihanna travels in style to her show at London's O2 Arena by taking the Tube

Meet the fans: She could not even get a seat in the standing room-only carriage but did not seem to mind as she chatted to passengers

She happily posed for pictures as she rode the Jubilee line and incredulous fans posted them on social networking site Twitter last night.

One fan en route to the show, Giselle Green told Mail Online: 'I was in Rihanna's carriage on the Jubilee line.

'I didn't really twig at first because you wouldn't expect to see a superstar travelling so casually on the tube. And she was due on stage in a couple of hours! But then me and my friend realised it WAS her.

'She was so cool and friendly and happy to pose for photos. I asked why on earth she was taking the Tube to her own concert.

And she said she'd always wanted to go on the Tube and decided to do it as it was the first night of her tour.'

Rihanna was cutting it fine as she was spotted on the train at 6.45pm, just 15 minutes before her support act, DJ Calvin Harris was due to go on stage.

A stunned Giselle chatted away to the superstar who was crammed into the rush hour carriage.

She said: 'Earlier in the day I'd jokingly posted on Facebook, "D'you think Rihanna will mind if I wear trainers tonight at her concert. Standing in heels for five hours would be HELL!"

'So when I chatted to her on the Tube, I asked her. And she said, "I wish I could wear trainers on stage!"'

Although the star was flanked by a huge entourage as she approached the ticket barrier she passed through with her very own Oyster card.

'She was so humble and normal,' Giselle added.

It was a fun start to what soon turned into the usual provocative antics seen onstage during the worldwide Loud tour which started back in June.

Strutting her stuff: Rihanna walks around the O2 stage in her barely-there jewelled bikini and nude fishnets

Last night she arrived wearing a bottom-skimming blue jacket but quickly stripped down to a barely-there jewelled bikini, nude fishnets and neon platform boots.

Her appearance came just days after northern Irish farmer Alan Graham ordered the Barbadian singer off his land after she stripped down for a music video earlier this month.
