Jennifer Lopez gave birth to a boy and a girl early today after one of pop music's most closely-watched pregnancies.
The babies were born at 12.45am local time (5.45am UK time) on Long Island, New York State.
Lopez, 39, and husband Marc Anthony, 38, married in 2004. The twins are her first children, and his third and fourth.
Lopez's publicist Simon Fields said: "Jennifer and Marc are delighted, thrilled and over the moon."
Lopez confirmed her pregnancy at a Miami concert in November, ending months of speculation.
Her father, David Lopez, told a TV station earlier this month that she was expecting twins.
