British pop star La Roux has postponed a show on her U.S. tour due to "extenuating circumstances".

The singer is due to kick off her American trek on 19 September (14) in Seattle, Washington, but she has now disappointed fans in Utah by calling off her planned concert in Salt Lake City on 26 September (14).

A post on her page reads, "Due to extenuating circumstances, the 26/9 show in Salt Lake City is postponed. Request full refunds from point of purchase. LR Management."

No further details about the reason for the postponement had been revealed as Wenn went to press.
