Kirsten DunstKirsten DunstSo there's been a lotta explosive chat surrounding Kirsten Dunst lately.

Whisperings that her reps have been quick to deny.

First up, reports came in a while back that Kirsten had been admitted to exclusive rehab facility Cirque Lodge, after a period of heavy partying at last month's Sundance Film Festival.

But her peeps are insistent that the 25-year old actress "is not being treated for cocaine or any drug".

Kinda like a process of elimination, this. But anyways, drugs are out - that's always good news.

Her reps were also quick to slam a report filed by American magazine Us Weekly, which alleges that Kirsten's ex, Jake Gyllenhaal, split with her because of her party-hard ways.

Jake GyllenhaalJake GyllenhaalA source quoted in the magazine claims that Jake, who dated Kirsten for over three years, was "turned off by all the partying".

But word from Kirst' corner has it that such chat is "downright wrong".

Jake and Kirsten broke up for good in December 2005, and Jake is now dating Reese Witherspoon.
