Singer Jennifer Lopez has fuelled speculation she is pregnant with twins after ordering matching outfits for a baby boy and a girl. The 38-year-old, who is expecting with her husband Marc Anthony, has asked for monogrammed babygrows from a top Los Angeles boutique - a blue version with the word 'Prince' and a pink one labelled 'Princess'. Lopez has registered for the gifts at luxury store Petit Tresor. She is also reported to have requested two Moses baskets, teddy bears with blue and pink ribbons and a jogging stroller to carry two infants, according to MSNBC.com. The most expensive item on the list is reported to be an enamelled black pram which retails at $3,495 (GBP1,748). Lopez confirmed her pregnancy last month (Nov07) while on stage with her husband at a concert in Miami, Florida.
