The 'Booty' singer was every inch the sizzling yummy mummy as the stepped out in Los Angeles for the star-studded event, which was held to honour artist Barbara Kruger and director Quentin Tarantino.
One word - wow!
Stealing the limelight from all the other celeb attendees (which included Kim Kardashian West and Cara Delevingne), J-Lo was the belle of the ball as she sauntered down the black carpet in a ravishing midnight navy gown designed by Gucci.
Her fabulous designer frock dazzled in the light and featured a floor-skimming train along with a mega-sexy plunging neckline, showcasing more than a hint of her décolletage. Ooer!
Oozing va-va-voom for her evening, the songstress styled her caramel locks in soft, tumbling waves which she swept over her shoulder while slicking her nails a deep navy metallic hue.
She also matched her mani to her arm candy with a luxe satin clutch, finishing her look with bronzed sunkissed cheeks, warm brown smoky eyes and fluttery false lashes along with a slick of apricot nude lipgloss on her pout.
After seeing her smouldering outfit, we bet ex-beau Casper Smart is kicking himself for not holding on tighter to his former missus. What a hot mama!
