Rihanna may have caused a media frenzy twice in the past nine months for riding the underground; and legend has it that Chris Martin and Gwyneth Paltrow have managed to sneak on the Tube largely unnoticed.
However, that's nothing compared to a hoard of Jennifer Lopez's boarding the Jubilee line from London's Baker Street Station. Question is, where are they headed?
Here are our suggestions:
1. She's putting the finishing touches to a new studio album. 2. She's about to announce a Greatest Hits collection. 3. She's hauling herself and several stunt doubles over to the O2 Arena to draw up plans for the UK leg of her world tour.
We wouldn't mind any of these three happening, though we know which one we'd prefer. Either way, we'll all be finding out what's going on tomorrow.
