Lambert, who turns 27 Wednesday, is vying for the top award at tonight's 44th Country Music Association Awards with fellow first-time nominees country trio Lady Antebellum and the Zac Brown Band, along with former winner Keith Urban and Brad Paisley.

Paisley, who is also hosting the awards show with Carrie Underwood, has been nominated for the award every year since 2005. Though he's won 13 CMAs since first being nominated in 2000, he's never won the biggest award.

With her 2009 platinum album, "Revolution," Lambert is the top nominee with nine nominations, the most for a woman in the 44-year history of the CMA's and the second most overall.

Both of her No. 1 hits, the sassy "White Liar" and the moving "The House That Built Me," are nominated in two categories, song and single of the year. She is also up for Female Vocalist of the Year, where she's up against last year's winner and Entertainer of the Year, Taylor Swift.

Lambert, along with Paisley and Lady A, who garnered the second most nominations this year with five total, are among the performers at the CMA Awards, which air live on ABC at 8 p.m. EST.

The show will also mark the debut singing performance of Oscar winner Gwyneth Paltrow, who stars with Tim McGraw in the upcoming movie "Country Strong."
