PROUD PAPA: At the Marni show, owner Renzo Rosso was still glowing from the experience of becoming a father once again in December. “I’m enjoying it so much. I can just hold her and cuddle her all the time,” he said of the new baby he’s had with companion Arianna Alessi, smiling and holding a hand to his breast. The baby girl is named Sydne since Rosso wanted a name with five letters — his lucky number. At age 60, this is the seventh child for Rosso, and the fifth girl.
