Designer Roberto Cavalli has confirmed what has been rumored for months: Yes, Jennifer Lopez is pregnant.

(And as the man charged with designing outfits for her changing body, he should know.)

Asked what types of clothing he designs for his celebrity clients, he told PEOPLE exclusively on Tuesday, "Well Jennifer Lopez, at this moment, she requests something very special because she is waiting for the baby.

"It is so complicated because every week she is getting bigger," added the designer, speaking from his celebration promoting Roberto Cavalli Vodka at his New York showroom.

Cavalli designed multiple loose-fitting and flowing outfits for the 38-year-old singer, who is on tour with husband Marc Anthony. (See PEOPLE's photo gallery of Lopez's fashion choices.)

"The thing about Jennifer Lopez, she is a singer, she is a dancer," said Cavalli. "Most of the time when I prepare something for the tour, the performer, they want something very soft so they can dance and so they can move free."

Earlier this month, Anthony raised eyebrows during the couple's show in Los Angeles when he sang a special dedication to his wife. "It's a real personal song," Anthony said before belting out Journey's "Faithfully," which includes the lyrics, "They say that the road ain't no place to start a family ..."

A rep for Lopez did not immediately return calls for comment.
