The venue is closed to allow for repairs.
The Lumineers, Simply Red and UB40 have all had to reschedule shows at the O2 Arena in London, after Storm Eunice ripped off part of its roof.
The venue won't open until at least Friday, to allow for repairs.
Those artists have got new dates - but details are yet to come out about rapper Dave's postponed concerts.
He was supposed to perform tonight and tomorrow.
