New York — Cameron Diaz turned up at the screening of Shrek Forever After during Tribeca Film Festival smoldering hot! She wore a Little Black Dress and accessorized with Lanvin black satin Genereux bag ($1260) and Lanving Spring 2010 pumps. Access Hollywood in its footage from the event claims that Cameron wore Lanvin LBD, but we were unable to locate the dress as part of any Lanvin runway collection. By the way, Victoria Beckham Fall 2010 Collection features similar LBDs.

NEW YORK– We caught Rihanna shopping at Barneys NY on Madison Avenue and having dinner at Da Silvano Restaurant last Tuesday (8/11/2009). Rihanna was dressed in a Rag & Bone sheath floral print dress ($276.75 at Barneys) and BALMAIN Ankle Fringe flats [sold out was $525 at Chickdowntown]. It’s nice dress, but we’d rather see Rihanna wear it with heels, not flats.

Rihanna carried an obscene oversize clutch that read something like this (in sequin), “such a f*ing lady wait your torn.”
