EXCLUSIVE: Shania Twain Stuns at CMT Artists of the Year Event, Reveals How She Stays in Incredible Shape

Shania Twain SLAYS in Nashville, and gets real with ET about her diet.

It's safe to say Shania Twain is looking amazing these days.

The 51-year-old singer slayed at the CMT Artists of the Year event in Nashville, Tennessee, on Wednesday, sporting a figure-hugging black La Petite Robe di Chiara Boni jumpsuit. ET caught up with the legendary country star, who gave us her secrets to maintaining her incredible figure.

"I just have to fight eating a lot of my favorite foods like french fries and any carbohydrates, which is a real drag," Twain admits to ET's Sophie Schillaci. "I have to just try to dominate my diet with more proteins. I love vegetables anyways, so that's OK, but it's just really hard keeping the carbs down, but that's what I do! That's my discipline -- keeping the carbs down."

Twain also maintains an active lifestyle.

"I play a lot of tennis. I love horses so I'm riding all the time," she adds. "I like just staying active."

Of course, Twain definitely has a few cheat days on occasion!

"My favorite junk food is dill pickle chips. It's a Canadian thing!" she shares. "I love a lot of cheat things but I try to balance it out and reward myself when I know I've done really well. Like, after tonight, I'm gonna pig out on something really bad!"

Twain received the Artist of a Lifetime honor at the event, and was serenaded with a medley of her biggest hits by Meghan Trainor, Jill Scott, and Kelsea Ballerini. The trio brought down the house with her 1999 hit, "Man! I Feel Like a Woman!"

"It just surprised me," Twain says about being chosen to receive the prestigious award. "I didn't expect something like this so early in my life. I guess if I could say it that way, I have lived a lot so much already in my life."

"I've had such a long career already, but when I look at all the years left, and all there is still left to achieve, I guess I just thought, 'Wow!'" she adds. "I was overwhelmed I guess I could say. It was very emotional."
