Madonna went to Justin Timberlake's concert in London and tried to be discreet, but you can spot Madonna a mile away.

“She was texting on her mobile, eating crisps and yawning just before the show began!” according to one fan report. Madonna was wearing a black hooded cape and was surrounded by bodyguards. “When everyone realized it was her and started chanting ‘Madonna!’ she put the hood on and went under the seat.”
