The 27-year-old stunned the guests at a lavish Oscars do by dragging gorgeous Twilight actor Robert Pattinson, 22, outside to the garden for, er, private time.
We watched aghast as the likes of the Olsen twins and Paris's ex Benji Madden stood open-mouthed at her antics.
Guests at the Patrick Whitesell's bash in the Hollywood Hills saw Paris go into overdrive trying to snare her man.
It became the talk of the party as we got a flirting masterclass from the hotel heiress.
She started off by dragging her little sister Nicky around the mansion hunting for her prey and when she found the Brit star she wasn't going to let him go.
They were giggling and in deep conversation for an hour before she led him to the garden for some privacy.
Unfortunately for her Robert left at 4.30am to fly to Japan. Lucky escape, mate...
