Leonardo DiCaprio "should have checked his facts" before his climate change speech at the Oscars, Stacey Dash has said.

Stacey is certainly no stranger to controversy, and her appearance at last month's Academy Awards (Feb16) was met with some confusion.

When host Chris Rock poked fun at the diversity debate by introducing the "new director" of the Academy's "Minority Outreach Program", Clueless actress Stacey walked out to a smattering of applause and said, "I cannot wait to help my people out. Happy Black History Month." Her quip wasn't received well though, with audience members and viewers alike taking to social media to question her being there.

Now the 49-year-old has courted scandal once again by commenting on Leonardo's decision to use his acceptance speech after winning Best Actor for The Revenant to raise awareness of the issue of climate change.

In a lengthy blog post entitled "Leonardo DiCaprio, quit being Chicken Little – the sky is not falling", Stacey accused the actor of having the wrong information.

She began: "Leonardo DiCaprio’s Oscar was truly a well deserved win. DiCaprio’s speech, you could tell, was planned ahead of time. He knew he had it. Though I’ve not seen his film yet, I hear it’s great. But this part of his speech was too much..."

Stacey then cited a section of Leonardo's speech in which he said: "Climate change is real, it is happening right now. It is the most urgent threat facing our entire species, and we need to work collectively together and stop procrastinating.

"We need to support leaders around the world who do not speak for the big polluters, but who speak for all of humanity, for the indigenous people of the world, for the billions and billions of underprivileged people out there who would be most affected by this. For our children’s children, and for those people out there whose voices have been drowned out by the politics of greed."

She continued: "He reminds me of Chicken Little, the bird who ran around the neighborhood and disturbed everyone 'with her foolish alarm.' (sic)"

The actress continued to cite information from Newsmax and Reason magazine, who both refute the claim that humans are responsible for, and continue to affect, global warming.

"There are people 10 miles from Leo starving, stuck on entitlement. Twenty first century NAZIS to deal with and North Koreans playing with nukes," she wrote. "He needs to get his priorities straight."
