Caressing her bump, singer Róisín Murphy, who is due to give birth late next month, disclosed she has just finished an eyewear line in collaboration with London specialist Linda Farrow. “They’re very bling, in gold and platinum plating,” she said Friday at Martin Margiela. So has she had any cravings? “Food in general,” she laughed. “The funny thing is you know exactly what you want to eat and when you want to eat it. It’s like, ‘Club sandwich. Now!’” Italian actress Valentina Cervi said she’s gearing up to promote her new film, “Sleepless,” a black comedy due to open in Italy later this month.
