Denise Richards threatens to spill everything about Charlie Sheen

Denise Richards is so furious about being accused of courting the media following her ex-husband Charlie Sheen's arrest, that she has threatened to spill everything that happened between them.

According to PopEater.com, the reports started when Richards, 38, was seen taking her children to a park where she was photographed by the paparazzi.

When some accused her of using the day out for a photo op, Richards insisted that it was just an average afternoon with her daughters, Sam, 5 and Lola Rose, 4.

"For all the negative nellies out there, I DID not have a f..ing photo op with my kids at a park. when there is drama u get followed more," the New York Daily News quoted her as writing on Twitter.

"Sorry had to vent s*** pisses me off sometimes..One day..I will spill my guts about EVERYTHING," she added.
