Usher and Tameka Foster (6 months pregnant!) called off their wedding which was supposed to go down THIS AFTERNOON in the Hamptons - here’s the official statement:

A statement released by Usher’s publicist, Patti Webster, said, “It was announced today that the wedding ceremony for Usher Raymond, IV and Tameka Foster was canceled. No additional information will be given regarding the circumstances of the cancellation, but we hope the privacy of this matter will be respected.”

Usher and the much-older Tameka (he’s 28, she’s 37) are expecting a baby this fall. No word on whether the couple is still engaged or even together.
