Lady GaGa left fans upset after she withdrew from two concerts in Manchester over the weekend.

The US singer was due to support Take That at Old Trafford Cricket Ground on Saturday and Sunday.

But a spokesman told the BBC the star was “feeling unwell” and “currently resting on doctor’s orders”.

No explanation was given to fans in Manchester when Lady GaGa failed to appear onstage on Saturday.

Instead, she was replaced by singer Gary Go, who appeared an hour later than originally scheduled.

Take That’s Gary Barlow is believed to have expressed his anger over the singer’s no show at the concert.

During an apology, he told fans: "'Don't get me started, you should have heard me backstage'."

As previously reported, Lady GaGa wowed fans at the Glastonbury festival on Friday with two separate performances.
