The US star won't perform tonight (Feb 25) in Glasgow

Alicia Keys has postponed two UK gigs this week due to illness.

The US singer has contracted laryngitis and has been told by a doctor to rest her voice, according to her publicist.

Keys will not perform at Glasgow’s SECC tonight (Feb 25), or at Manchester’s MEN Arena the following day.

The cancelled dates, however, are likely to be rescheduled.

Keys picked up two Grammy Awards earlier this month for her recent single, ‘No One’.
