Susan BoyleSusan BoyleThe life of a pop star is no walk in the park.

As Susan Boyle is learning quickly.

The Britain's Got Talent runner-up has reportedly pulled out of another show.

According to The Daily Mirror, there's been oodles more drama surrounding Su-Bo and the BGT live tour.

The paper reports she pulled out of a concert last night in Liverpool and that she has now returned home.

They allege she stood on the balcony of her hotel asking for her cat, Pebbles.

Su-Bo also missed a gig last Sunday in Manchester after doctors ordered her to rest.

A BGT spokesperson denied the talk of Su-Bo asking for her cat and told The Sun: "Susan's just tired. She has gone for a sleep and a bit of rest."

Organisers of the tour have now confirmed that Susan will not be performing at tonight's live show in Cardiff, either.
