Star USHER’s would-be bride TAMEKA FOSTER has denied rumors the couple have split, just days after their wedding was inexplicably cancelled.The pair were due to wed on Saturday, but the nuptials were called off allegedly due to a string of differences in opinion between the couple and Usher’s disapproving mother. But Foster insists the reasons for postponing the wedding presented by the press are wide of the mark. She says, "No-one knows why we cancelled the wedding, but I can tell you that all of the reasons everyone is speculating and writing about are completely untrue." Pregnant Foster admits, however, she did check into hospital at the weekend after she fell victim to pre-term labor: "We had a scare. But, I am fine and the baby is fine." Usher announced his stylist girlfriend Foster was pregnant in January and the couple confirmed engagement reports in June.
