Lambert earned seven CMA nominations, including her first entertainer of the year nomination in five years.
The Grammy winner was pushed by the success of songs such as Bluebird, her first country airplay number one in years, as well as positive reviews of her album Wildcard.
She is followed by Luke Combs, who continues his streak of success as one of country music’s biggest streaming artists with six nominations, including his first for entertainer of the year.
Combs earned his first all-genre number one album last year with What You See Is What You Get, which had the largest streaming week ever for a country album with 74 million on-demand streams.
The CMA Awards are normally held in November in Nashville, although details on this year’s awards show have not yet been released.
Dan + Shay’s Dan Smyers has six nominations, including four he shares with bandmate Shay Mooney and three with pop star Justin Bieber for their crossover hit 10,000 Hours.
Smyers earned individual nominations for his work as a producer on the song.
These are the first CMA nominations for Bieber, who won a CMT Music Award in 2011 for That Should Be Me with Rascal Flatts.

Carrie Underwood joins Lambert and Combs in the entertainer of the year category, along with Keith Urban and Eric Church.
Garth Brooks, who won last year, recently announced he no longer wanted to be nominated for entertainer of the year because it was time for others to win.
Other top nominees include Maren Morris, who scored five nominations including song and single of the year for her love song The Bones.
Her track became the longest-running number one on Billboard’s Hot Country Songs chart by a solo female artist since Taylor Swift’s We Are Never Getting Back Together.
Producer Jay Joyce also earned five nominations for his work on albums by Lambert and Ashley McBryde, who earned three nominations including album of the year and female vocalist of the year.
After years of criticism for the lack of women on country radio, women actually outnumber men in the new artist category, with nominees including Carly Pearce, Gabby Barrett and Ingrid Andress.
Pearce earned three more nominations for her duet with Lee Brice, I Hope You’re Happy Now, which was co-written by Combs.

Barrett, who competed on American Idol, earned a nomination for single of the year with I Hope, a number one country hit and Top 10 success on the pop charts.
Andress was nominated for song of the year with More Hearts Than Mine.
Morgan Wallen and Jimmie Allen round out the new artist nominees.
Notable snubs missing from the nomination list include country star Tanya Tucker, who earned her first two Grammy Awards this year for her comeback album While I’m Livin’.
The Chicks, who returned with their first new album in 14 years, were also not nominated, probably due to a longstanding rift between some country fans and the outspoken female group.
Sam Hunt, who put out a long-awaited album this year, was also missing from the nominations.
The coronavirus pandemic is likely to have affected some of the nominations this year because touring was postponed and some albums were pushed back.
Luke Bryan, who delayed his album until after the cutoff deadline for this year’s awards show, was not nominated.
