Jennifer Lopez wore a white KaufmanFranco dress on the red carpet at the Las Vegas premiere of her movie Parker last night. She and costar Jason Statham brought their thriller to Planet Hollywood in Sin City following a Wednesday-night screening in NYC. J Lo had lots of support from her guys last night, since her boyfriend, Casper Smart, posed for photos by her side. He also accompanied her and Jason to the afterparty inside the casino. Parker arrives in theaters today, and despite some initial critics not loving what they saw, today the New York Times reviewed Parker as a reasonably good thriller. Reviewer A.O. Scott wrote that the film is "great fun" and that director Taylor Hackford "knows how to pull off a caper without making a big deal about it."
