Dierks Bentley Asks ‘CMA Music Festival: Country’s Night to Rock’ Crowd ‘Am I the Only One’?

Nobody gets a crowd revved up like Dierks Bentley. During tonight's 'CMA Music Festival: Country's Night to Rock' special, Bentley asked the Nashville crowd 'Am I the Only One' -- and the answer was a resounding cheer.

Like a true guy's guy and a real country music heartthrob, Bentley's outfit was effortless, but his attempt was not. He sported a backwards baseball cap and a white T-shirt while he laid down his latest hit, and the thousands of women in the crowd responded appropriately.

We admit, we're suckers for a scruffy country star, and Bentley is about as primp-free as they come. Still, his performance is fine-tuned, and he even managed to stay afloat sandwiched between an amped up Rascal Flatts/Little Big Town number and a Miranda Lambert showdown.

The CMA Music Festival took place June 9-12, but the ABC 'CMA Music Festival: Country's Night to Rock' special found its way to television for the first time on August 14.
