Usher fans who were planning to see the 33-year-old hit maker at Aloha Stadium in December should make other plans for the evening.

Attorneys representing Usher notified the Honolulu Star-Advertiser on Monday that Usher will not be performing, and that the promoter, Memphis, Tenn.-based NuDawn Entertainment, "never had the authority to represent (Usher) in any capacity" and that Usher had "not approved or otherwise granted permission" to the promoter to make any commitments on his behalf.

The letter, which was also sent via email to NuDawn Entertainment, described the Aloha Stadium concert as an "Unauthorized Event" and demanded that NuDawn run advertisements "stating that the promoter of the Unauthorized Event never had permission to book the Unauthorized Event and (Usher) will not be appearing."

Calls to NuDawn Entertainment in Memphis, and to Usher’s management in New York and Los Angeles, seeking comment were not returned.

The Aloha Stadium Authority had approved use of the venue for a concert by Usher on Dec. 30, but its availability did not mean a concert would take place.

A spokesman for the Stadium Authority had no comment yesterday.

Usher’s most recent album, "Raymond v. Raymond," debuted at No. 1 on the Billboard Hot 200 pop albums chart in 2010 and has been certified platinum for sales of more than 1 million copies. He is also is a four-time Grammy Award winner with sales of more than 23 million records in the U.S. and more than 65 million worldwide.
