The always lovely Lauren Alaina had a terrific 2011, placing second on ‘American Idol’ and releasing her well-received debut album, ‘Wildflower.’ She capped off the year by performing her fast-paced single ‘Georgia Peaches’ on Fox’s ‘American Country New Year’s Eve Live’ special last night (Dec. 31) in Las Vegas.

Alaina was quite the stunner in her sparkly, long-sleeved black mini dress, which she paired with a sleek, pin straight blow out and smoky eye makeup. Alaina is in terrific shape, and her performance was as spot on as it gets. She looked great and sounded even better.

The teen had the packed crowd of people singing along with her, especially the “woah oh” part, as she turned in a flawless, high energy performance. It was clearly Lauren Alaina’s night (and her year), and she owned that stage in Sin City. It’s hard to believe Alaina is just 17 — and since she’s not old enough to enjoy libations on New Year’s Eve, she performed as though she was intoxicated by the music and the crowd’s energy.

Whether you watched the show in the comfort of your living room with a glass of bubbly or if you were there in the flesh enjoying in live, Alaina delivered a rendition of her hit single that was powerful enough to get blood flowing and adrenaline pumping.
