Crow and "An Inconvenient Truth" producer David walked over to the presidential adviser's table, where David suggested that Rove "take a new look at global warming." David said Rove was rude with her, but witnesses say David was very aggressive.

Rove said David came over to insult him and succeeded.

Crow tried to calm things down but was instead drawn into the debate with Rove, telling him, "You work for me."

Rove responded, "No. I work for the American people."

Writing about the encounter on The Huffington Post Web log, the Hollywood mavens gave a colorful recount of the discussion.

"In his attempt to dismiss us, Mr. Rove turned to head toward his table, but as soon as he did so, Sheryl reached out to touch his arm. Karl swung around and spat, 'Don't touch me.' How hardened and removed from reality must a person be to refuse to be touched by Sheryl Crow?" they wrote.

The two also weren't impressed by Rove's apparent argument that the United States would lose it's competitive edge by acting unilaterally.

"Like a spoiled child throwing a tantrum, Mr. Rove launched into a series of illogical arguments regarding China not doing enough thus neither should we (Since when do we follow China's lead?)," they wrote.

The two remained in Washington, D.C., Sunday for an Earth Day event on the campus of George Washington University. Expected to perform were Crow, Faith Hill and Tim McGraw. Speakers include David's husband, "Curb Your Enthusiasm" star Larry David, 2008 presidential candidate Sen.. John McCain and former Vice President Al Gore.

Speaking to FOX News ahead of the concert, Crow said global warming should not be a partisan issue.

You know what, this is not about politics, okay, we're all guilty and we all have to be part of the solution. This is, now, this is is about all of us, we all want clean air and water. The environment is like a spring day and a shady tree. It doesn't belong to any one particular party or group, it's about all of us, that's an important message for Earth Day today," she said without mentioning the encounter with Rove.
