It looks like Paris Hilton is on a global mission to hunt down Robert Pattinson.

The hotel heiress - who flirted up a storm with the heartthrob actor at the weekend - arrived in Tokyo just hours after Robert touched down in the city ahead of Friday's Twilight premiere.

According to multiple sources, the reality TV star dragged little sister Nicky around Patrick Weitzell's post-Oscars bash as she hunted down her prey.

And when she found the British actor 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," says an eyewitness.

But, fortunately for Robert, Paris may well have moved on.

The Simple Life star arrived at Narita International Airport with rumoured new beau Doug Reinhardt, former star of The Hills and Lauren Conrad's ex.

Paris is in Tokyo to promote clothing brand Samantha Thavasa.
