PENELOPE Cruz didn’t look pregnant, but Javier Bardem‘s girlfriend wore a big sapphire surrounded by diamonds on her left ring finger at Paper magazine’s dinner for her and director Pedro Almodovar at Casa Lever Saturday night. Madonna snuck in a back door to join Debbie Harry, Isabel and Ruben Toledo, Paige Powell with new beau Jeffrey Deitch, Sean McPherson, Serge Becker and Joey Arias. Paper’s cherubic columnist Mickey Boardman was presented with a surprise birthday cake and a song by Metropolitan Opera counter-tenor Anthony Costanzo.
