J. Lo celebrates her pregnancy in style. Jennifer Lopez has given out a baby shower in a Swarovski crytal-covered room.

The 38-year-old Lopez and husband Marc Anthony have attended the blue and pink theme afternoon party, which is hosted by producer Elaine Goldsmith-Thomas. The guests include designer Robert Cavalli and actress Leah Remini. Cavalli gave her a pink leopard crib, a witness says.

According to a source, Lopez "looked very pretty - and very pregnant." Last month, her sister Lynda Lopez gave her matching pink and blue onesies, which fueled reports once more that the Latin singer is expecting twins.

Her pregnancy was first announced at their El Cantante tour in November where Lopez told the audience, "This is a special time in our lives."
