Usher, who tied the knot at his lawyer's offices, told Us Weekly magazine: "It was beautiful and private. We didn't have a first dance - but we had a lovely, intimate dinner filled with candlelight and flowers.
"We're going to have a larger wedding ceremony sometime later in the year, or after the baby is born, so we can prepare for the birth of our first child."
Tameka, who is expecting Usher's first child, is due to give birth in the autumn.
The couple's low-key nuptials took place just days after their original ceremony at record executive L.A. Reid's Hamptons estate was canceled at the last minute.
The singer - real name Usher Raymond - allegedly called off the lavish wedding just two hours before the ceremony was due to begin because his mother and former manager Jonetta Patton didn't approve of the union.
