Jennifer Lopez's husband Marc Anthony has given her a $300,000 diamond ring to celebrate the birth of their twins.

The 'Do It Well' singer, who delivered son Max and daughter Emme on February 22, was thrilled when Mark presented her with the stunning eight-carat yellow canary diamond ring.

A source close to the singer said: "Jennifer wasn't expecting such a generous gift, but Marc wanted to give her something to remember the day by."

Meanwhile, Jennifer - who is believed to have spent a staggering $1.4 million on giving birth in a luxurious birthing suite at Long Island's North Shore University Hospital - has hired exclusive Los Angeles baby boutique Petit Tresor to design a nursery in the couple's Puerto Rican estate.

The 38-year-old star, who reportedly received $6 million for the first photo shoot with her babies, recently employed a masseuse and color therapist for the newborn twins.

Jennifer is also said to have ordered two Shetland ponies for Max and Emme, along with diamond-encrusted rattles, 600 thread count Egyptian cotton for the baby's cots and designer babygros for the nursery wing in her Los Angeles home.

The 'Wedding Planner' actress recently revealed becoming a mother is the best thing that has ever happened to her.

She said: "Your heart is connected to them. With all the things that Marc and I have accomplished in our lives, this is the biggest thing that will ever be."
