Rihanna On The Tube: "I Need To Max Out My Oyster Cards!" - Audio

The 'You Da One' singer says she now has three Oyster Cards for when she is back London.

Rihanna has vowed to max out her Underground Oyster Cards on future trips to London, after being pictured taking The Tube earlier this week.

The 'We Found Love' singer was spotted boarding a train at Waterloo Underground Station this week on her way to watch Drake in concert, and confirms she now has her very own Oyster Card for when she is in the UK again.

"Of course I am!" Rihanna told Capital's showbiz reporter Kevin Hughes, about whether she will be back on the Tube again. "Even if I didn't want to before I've got three Oyster Cards in the last 24 hours!

"So I don't have a choice now!" Rihanna joked. "They're all topped up. I need to, like, max them out!'

The 'You Da One' singer previously took the Tube in November 2011 on her way to the O2 Arena for her 'Loud' tour, and again more recently for the BRITs 2012 rehearsals in February, after insisting that it was a more convenient way for her to travel.

Earlier today Rihanna confirms she is currently in the planning stage of her next world tour which she says will begin in 2013.
