If Rihanna was really trying to blend in with the masses, she should have worn some pants!

On Tuesday night, the "We Found Love" singer hopped on the London Underground (the city's subway system) wearing a leather jacket, hip-high leather Christian Louboutin boots and a shirt with flames emblazoned on the front.

The blonde singer topped off her look with Ray Ban Wayfarer sunglasses and a bold red lipstick.

On her way to watch fellow music star Drake take the stage at the O2 Arena in the Greenwich neighborhood of London, this trip wasn't the first time the 24-year-old has opted for mass transportation — she also took the train to her rehearsal for the BRIT Awards in February.

"There's so much traffic. It's an hour and a half to the O2 but it's 10-15 minutes on the Tube," the Daily Mail has her saying.

Rihanna has been loving her super-luxe, super-sexy Louboutin boots, which she has been spotted traipsing throughout the UK in, as she films her yet-to-be-titled reality competition show.

Last month, she paired the fanciful footwear with studded daisy duke shorts with a chambray button up, gold hoop earrings, Wayfarer sunglasses and a trucker hat.
