British singer Amy Winehouse has infuriated fans by cancelling another gig - and has been advised by doctors to "rest" for the foreseeable future. The Rehab star was due to perform at the T In The Park festival in Kinross, Scotland on Saturday (07Jul07), but pulled out of the gig at the last minute, blaming the no-show on "exhaustion". Her spokesman says, "Following a year of non-stop touring and promotion, Amy has been advised by a doctor to take time off and rest. Amy would like to apologise to fans for this cancellation." The star had previously cancelled a gig at Liverpool's Summer Pops festival on Wednesday (04Jul07).
