We'll have to update our celebrity birthday calendar.

Jennifer Lopez and husband Marc Anthony are now the proud new parents of twins, a boy and a girl, Lopez's manager has announced to a curious world of entertainment news reporters.

The babies were born early Friday in Long Island, New York. The girl was born at 12:12 a.m. and weighed 5 lbs. 7 oz.; the boy followed at 12:23 a.m., weighing 6 lbs.

"Jennifer and Marc are delighted, thrilled and over the moon," manager Simon Fields told People magazine.
