Smash, indeed!

Debra Messing goes toe-to-toe with Maria Menounos in the May issue of Allure -- posing completely nude for famed celebrity photographer Patrick Demarchelier in a stunning black-and-white pictorial.

Lounging on a rumpled bed, the Smash actress, 43, wears nothing but a bejeweled ring and bracelet and a seriously seductive stare -- showing off her toned, slim physique and backside. Since separating from husband of ten years Daniel Zelman late last year, Messing has been quietly dating Smash costar Will Chase; she and TV producer Zelman share son Roman, 7.

Ten years Messing's junior, 33-year-old Menounos also poses in the buff for Allure, similarly showing off her flawless bod as she hangs out on a bed without a stitch of clothing. The single Extra! correspondent and current Dancing with the Stars competitor has stripped down somewhat before -- most famously showing off her bikini bod in Times Square in February following a lost Super Bowl bet -- but the Allure spread is the TV personality's first nude snapshot.
