Jennifer Lopez, shown on Feb. 6, is "thrilled," her manager says, after giving birth to twins early Friday morning in New York City.

Jennifer Lopez gave birth to twins early Friday in New York, 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, said. 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.

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