Jennifer Lopez expecting twins?

Jennifer Lopez has ordered matching baby supplies for a boy and girl, sparking rumours that she is expecting twins.

The singer, who announced that she is pregnant by husband Marc Anthony last month, has registered a gift list with Los Angeles baby boutique Petit Tresor.

Her requests include monogrammed blue and pink babygrows labelled 'Prince' and 'Princess', two Moses baskets, teddy bears with blue and pink ribbons and a £1,748 enamelled black pram.

She has also asked the store to design nurseries at the couple's homes in Bel Air, Fisher Island, and Oyster Bay.

A friend told the New York Daily News that Lopez is spending $40,000 on each room, saying: "She wants them filled with the most chic furniture from Europe and embroidered linens from France."
