Boyle 'may sing in Cardiff tonight'

Susan Boyle has missed another live Britain's Got Talent concert, it has emerged.

The show runner-up stayed in London and did not perform in Liverpool last night but may return to the tour for tonight's gig in Cardiff, The Sun reports.

A spokeswoman said: "Susan's just tired. She has gone for a sleep and a bit of rest."

Boyle played the first three shows of the ongoing tour but missed two concerts in Manchester before returning to the lineup in Glasgow.

It was previously confirmed that the singer would only perform at selected shows on the nationwide tour.
