Washington, July 30 (ANI): R and B star Usher's July 28th wedding to Tameka Foster was reportedly called off because of a series of differences between the pair.

The superstar was looking forward to marry his pregnant fiance at record executive Antonio 'L.A.' Reid's home in Long Island, New York.

But the ceremony was scrapped just hours before the ceremony, allegedly due to a string of disagreements between the couple, as well as Usher's mother's disapproval of the awaiting nuptials.

"Usher's mother [and former manager, Jonetta Patton, whom he fired in May] is against the wedding. That is one of the main obstacles. They only decided two weeks ago to have a wedding. They wanted to have it take place before the baby bump started showing," People quoted a source, as saying.

However, another source revealed that it was Usher who decided against the marriage at the eleventh hour, because of past few rough days between the pair.

"Usher changed his mind. They had a lot of differences about the details. For example, the bride wanted barbeque, [and] he wanted to have [renowned chef] Jean Georges cook," the source said.

The source added that as a result of the differences, the wedding "was on again off again for the past few days. [Foster] was calling it off because she wasn't getting the things that she wanted. The mother was calling it off. ... Usher was calling it off."

Usher's spokeswoman, Patti Webster issued a statement on the same day of the cancelled wedding refusing to comment on whether or not the couple had split.

"It was announced today that the wedding ceremony for Usher Raymond IV and Tameka Foster was cancelled. No additional information will be given regarding the circumstances of the cancellation, but we hope the privacy of this matter will be respected," Webster said.

Usher confirmed the pregnancy of his stylist girlfriend Foster in January this year and the couple confirmed engagement reports in June. (ANI)
