Pictures: Rihanna Rides Subway to Her Concert with Fans

| by Michael Allen

Rihanna is a millionaire at the age of 23, but recently took the subway (or as they call it in England the 'tube") and traveled along with her fans to her concert at the O2 Arena in London.

The singer could not get a seat in the standing room-only subway, but did not seem to mind as she chatted with passengers including a group of teenage girls. She happily posed for pictures, which fans posted on the social networking site Twitter.

Rihanna was cutting it close 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.

Although the star was flanked by a huge entourage as she approached the ticket barrier, she passed through with her own subway pass.
