Is Chris Martin is one of the world's most unrecognizable rock stars?
The Coldplay frontman tells Britain's Mirror that not a soul recognized him when he hopped on an underground train to get to his band's recent sold-out London concert.
What's worse, when he arrived at the O2 arena, "Security stopped me at the door and I had to explain who I was. That was a bit embarrassing."
Maybe Martin should just carry a photo of Gwyneth Paltrow with him.
