Superstar singer Celine Dion has axed more shows in Las Vegas after she failed to recover from a throat condition in time to make her stage return.

The My Heart Will Go On hitmaker called off a series of Sin City concerts earlier this month (Aug14), putting her residency at Caesar's Palace's The Colosseum venue on hold as she battled inflamed vocal cords.

She was due to return to the stage on Friday night (08Aug14) for her first show back after her bout of ill health, but the concert was called off as Dion is not yet well enough to get back to work.

She axed Friday night's show, as well as dates through to 13 August (14).

A statement posted on the singer's website reads, "Celine has been receiving treatment for acute inflammation and swelling in the muscles adjacent to her vocal cords. After being examined by her physicians... it was determined that she will require further rest in order to achieve a 100 per cent recovery."

Dion is now due to resume the residency on 15 August (14).
