New York, July 16 Oscar-winner Penelope Cruz's growing frame has sparked speculation that she may be pregnant.

Her bigger frame was first observed in May, when she walked the red carpet at the Cannes Film Festival. She also became ill due to "food poisoning" at the time.

The New York Post has now reported that Cruz looks plumper than before in a picture, which was clicked when she and her beau Javier Bardem were leaving a U2 concert in Paris.

Bardem is leaving in a few weeks to start shooting a movie in Bali with Julia Roberts.

Cruz's representatives have refused to comment on the speculation about her pregnancy. (ANI)
