It's not really news, she's a bit of a Tube fan (hur), what with her using it to transport her to play her concerts in the O2 last November. This time around, she thrilled her fellow tube passengers (lookit the fella in the red) by using public transport to see her mate Drake perform.
Fair play to her though, she could've spent a wedge on a hired driver to herd her entourage (which doesn't appear to include Ashton Kutcher as yet) about in a gas guzzler, particular since those groin-high leather boots look like they could chaff after a spell.
In case you're having trouble spotting Rihanna, WENN have kindly circled her in this photo.
Rihanna failed to take the Luas Red Line to the O2 when she last performed in Dublin. Can't imagine why.
