Nicole Kidman @ 2008 Country Music Awards

Nicole Kidman (in YSL) comes out to support her main man, country superstar Keith Urban, at the 2008 Academy of Country Music Awards on Sunday in Las Vegas.

The LA Times reports that the Oscar-winning actress took a spin class two days in a row – Saturday and Sunday – at Body and Soul gym on Santa Monica Blvd. in West Hollywood.

“Nicole tends to keep her head down when she spins which isn’t advised because it’s bad posture that cuts off your airway and lessens your oxygen intake,” said one spinner. “But if she keeps coming to [spin] class, she’ll learn good posture on the bike, which keeps your core engaged and your diaphragm open.”
