Singing legend Cher has spaked concerns over her health after she cancelled six shows at Las Vegas Caesar’s Palace in the past month.

The diva is recuperating from asthma-related bronchitis, according to the Sin City casino, where she backed out of shows on Saturday and Sunday.

According to Cher’s longtime rep, Liz Rosenberg, the 62-year-old entertainer is suffering from a simple case of “Vegas throat,” a condition caused by the dry desert air at the gambling resort.
