Usher 2921.jpgOK Magazine dropped a bombshell earlier this morning - apparently Usher's going to be marrying his longtime fiancee Tameka Foster this weekend! Unfortunately, the magazine hints at tension which might mar an otherwise picturesque wedding, alleging that several of the singer's longest-known associates (including his assistant of six years and his mother) didn't get an invite due to Foster's insistence. Hopefully the couple can come to an agreement before the big day - after all, it'd be a shame for any mother to miss her son's wedding!
