Stacked SALMA HAYEK blew her stack when dinner companion MELANIE GRIFFITH fired up a cigarette on the patio of trendy West Hollywood eatery Cecconi’s and puffed in the presence of Salma’s 18-month-old baby girl.

Instantly, Salma insisted that she smoke outside or douse her coffin nail pronto!

Melanie snapped that Salma needed to lighten up her parenting technique, and insisted the fumes wouldn’t waft anywhere near her tyke’s tiny nose.

While the wives bitched back and forth, hubbies ANTONIO BANDERAS and FRANCOIS-HENRI PINAULT wisely stayed out of the line of fire-and-smoke – then swiftly changed the subject as Melanie sighed and took her smoky butt outside.
