The proud parents welcomed their son and daughter on February 22, Emme was born at 12:12 am and weighed 5 lbs. 7 oz., and Max followed at 12:23 am, weighing 6 lbs.

The babies have been under round-the-clock guard since their birth.

According to US reports Lopez is so worried that the twins might be kidnapped she paid £300,000 hiring a team bodyguards to watch over them.

Earlier this week it was revealed that the new mum had spent $1.4m (£700,000) on giving birth at New York's North Shore University Hospital.

But while that may seem a staggering amount to some - it's not so bad when you consider the $6million (£3million) she is getting for exclusive pictures of the babies.

The twins are the first children for Lopez while Anthony, 39, has three other children from previous relationships.

The 38-year-old and her husband's whopping bill includes $700,000 (£350,000) to reserve a luxurious birthing suite at the hospital.

The pair shelled out a further $300,000 (£150,000) on private doctors and nurses, $300,000 (£150,000) on security and $100,000 (£50,000) on personal assistants in the run-up to the birth.

J-Lo's luxurious birthing suite included white couches, a large Apple computer monitor, a private kitchen and two flat-screen TVs, according to a US magazine.

"She's doing so well but we have gone through a lot of tissues. Everyone is crying tears of joy," a Lopez pal told In Touch Weekly magazine.

Meanwhile gifts have been pouring in for Max and Emme, including pillows and baby carriers from Baby K'tan in Fort Lauderdale with their names embroidered on them, a source said.
