The Russian model looked tanned and toned as she arrived at the Vanity Fair bash, with her golden gown sweeping along the floor.
She flashed plenty of flesh with the glamorous look, showing off her toned back and slender arms.
And the superstar model accessorised the sparkling look with gorgeous turquoise earrings and a huge matching ring.
While Irina left footie ace fella Cristiano Ronaldo at home, the face of Replay Jeans definitely won`t have been without company for long.
She was joined at the exclusive afterparty by pop babe Jennifer Lopez.
The 42-year-old star looked half her age in a pretty red dress, combining see-through lace with metallic detailing.
The I`m Into You hitmaker threw even more attention on the floor-length flock by wearing her hair up off her face.
And she topped off the winning look with silver earrings and rings, as well as a clutch to match her gown.
But while J-Lo opted for a plunging neckline, she was seen later checking she`d managed to keep her assets inside her frock.
She wouldn`t want the whole dress to end up On The Floor.
