Rihanna is one down to earth Caribbean chick who never disappoints her adoring fans.

On Wednesday night, RiRi hopped a subway aka the “TUBE” for her own show at London’s o2 Arena.

“I cannot believe @Rihanna got the tube to the o2 tonight! But she did…,” one adoring fan Tweeted.

RiRi tweeted back saying, “WORD UP!!!”
