Miranda Lambert has been riding high since she won a Grammy for her 2014 album, Platinum, but that doesn't mean the singer didn't have a few reservations when she first heard about the nomination.

Apparently the Somethin' Bad singer felt a little intimidated by her fellow nominees, as well as "sad" that she was competing with such talented artists.

"I was pretty shocked," Lambert said of the nomination during an interview with Taste of Country on Feb. 9. "I was kinda sad when I saw the category, 'cause I was like, 'Mmm, it's pretty tough.' You know? There's some amazing albums in that category and I'm a fan of all of them."

Lambert found herself competing with Brandy Clark, Lee Ann Womack, Dierks Bentley and Eric Church for Best Country Album at the 57th Annual Grammy Awards in Los Angeles on Feb. 8.

Lambert was the only artist to be nominated in all five country categories this year, though she only scored one win. "I am so thankful for this," declared the singer during her acceptance speech. "I poured my heart and soul into this record."

Platinum earned Lambert her second Grammy win, having already won Best Female Country Performance for the The House That Built Me in 2011.

This month the country star will continue with her 2015 Certified Platinum Tour, which kicked off in January. Lambert is set to perform all across the country well into the summer.
