The twins are 38-year-old star Jennifer’s first children, while Marc, 39, already has three kids.

Jennifer – who announced her pregnancy during a concert last November, ending months of speculation – is reported to have given birth in a luxurious hospital suite. The room came complete with wooden flooring, a brown leather couch and two giant plasma TV screens.

The couple are said to be considering the names Max and Emme for their babies.

People magazine is rumoured to have offered the couple – who married in June 2004 – a staggering USD6 million for first pictures of the tots.
