Even when she's perfecting her tan, Sheryl Crow can't get George Bush off her mind.
Last weekend, the folks at Ritz-Carlton hired the Grammy winner to perform at the opening of their 60th hotel, on Grand Cayman. You may recall that Sen. John Kerry blamed the island — where Enron hid its massive debts — for America's tax-evasion problem. Though she campaigned for Kerry, Crow wasn't about to knock her host country, especially since the Ritz-Carlton had treated her to a week of scuba-diving and pina coladas.

But she couldn't entirely miss a chance to tee off on Bush.

Like his father, the President has sought to turn America into "an imperial power and create strongholds over oil-heavy countries in order for us to control and manipulate them," she told us. "Now, if we pull out [of Iraq] we are going to leave a complete and total mess. We don't even know who we're fighting over there."

Meanwhile, Crow deftly deflected questions about when she and supercyclist fiance Lance Armstrong plan to marry — and whether it's true they've been visiting fertility specialists.

"I read that," the 43-year-old stunner said with a smile. "That's very exciting. I hope it works out well for them." Crow recalled that, ever since she met Armstrong, she's been reading that "I've been going to fertility clinics, and that I got married in Portland about two years ago.

"I can laugh about it. But in the privacy of my own home, it grieves me, because those are such … personal topics. That somebody would feel they have the right to write about it is grotesque."

Also putting on the Ritz at developer Michael Ryan's resort was Tony Bennett, who delivered a swinging set. Others on hand included Marcia Gay Harden, Christopher Meloni, Chloe Sevigny and Steve Case. Rosario Dawson canceled at the last minute because, she said, "God told me not to come," said a source. No one partied later than "Entourage" star Adrian Grenier, who was spotted having breakfast with Gillian Turner, a fetching redhead.
