Singer Cher has rescheduled two "Dressed To Kill" concerts due to health issues.

The 68-year-old has postponed her shows after contracting an "acute viral infection," according to her representative, reports contactmusic.com.

Cher was scheduled to open the second leg of her tour with a show Thursday in Albany, New York, but this has been pushed to Oct 6. Her Manchester concert on Sep 13 has also been rescheduled for Oct 7.

She is on doctors' orders to rest in bed for a full seven days since she was examined over the weekend.
