Latest: R+b star Robin Thicke will sing at pal Usher's wedding in Long Island, New York on Today ()June 28th), according to the latest U.s. reports.

The Yeah! hitmaker will reportedly wed pregnant fiancée Tameka Foster at the Wainscott home of top producer Antonio 'l.a.' Reid.

The big day comes just a month after the couple confirmed their engagement and pregnancy.

One insider tells American magazine Life + Style, the wedding date was pushed up because of the pregnancy, explaining, "They were planning on getting married at the end of the year, but when Tameka found out she was pregnant, they rushed to have the wedding."

The magazine reports Usher's once-estranged father and his godfather, actor/dancer Ben Vereen, will attend the wedding ceremony. But the singer's mother and former manager, Jonnetta Patton, who disapproves of her son's relationship with Tameka, was not invited.

Wedding planner to the stars Diann Valentine is reportedly handling all the last-minute arrangements. Thicke will sing the bride and groom's favorite tunes and Harlem chef Sylvia will cater the event.
