Monday morning started off so well...
Unbeknown to Prince and Dan they were in for one hell of a few hours.
London commuters reported scenes of "absolute madness" and people "crushed" on the Victoria line.
The penny began to drop.
But it got worse.
It kept escalating.
And then an entire section of the line just gave up completely.
Prince and Dan have not tweeted for over two hours now.
For an unlucky few, the chaos continued even after they were out of the tube station.
Others were late for some crucial appointments.
A spokesperson for TfL said no one had been injured and normal safety measures to relieve overcrowding had been put in place.
There were no reports of injuries.
Victoria train station was also rather busy this morning.
