NEW YORK -- Jennifer Lopez gave birth to twins early Friday, making the singer and husband Marc Anthony the parents of a boy and a girl after one of pop music's most closely watched pregnancies.

"She's thrilled," Lopez's manager, Simon Fields, told The Associated Press. He said the babies were born "just after midnight this morning."

Fields confirmed that the girl arrived first, weighing 5 pounds, 7 ounces. "Her boy is 6 pounds even and arrived about 15 minutes later" at a Long Island hospital, he said. The location was not identified.

Ending months of speculation, Lopez confirmed her pregnancy at a Miami concert in November. Her father, David Lopez, told Telefutura's "Escandalo TV" earlier this month that the 39-year-old singer was expecting twins.

Lopez and Anthony, 38, married in 2004. The twins are her first children, and his fourth and fifth.
