Billie Eilish might be a “Bad Guy” to Lizzo and Lil Nas X fans — but she’s the best gal at the 2020 Grammys.

Grammys host Alicia Keys and 2019 Best New Artist winner Dua Lipa presented Eilish with the award for Best New Artist Sunday night during the telecast at the Staples Center in Los Angeles, Calif.

“Ay, ay, ay — TWO! I forgot to thank my touring team for helping me put on a show,” the 18-year-old Song of the Year winner said upon accepting her third award of the night. (She actually won the Best Pop Album honor in the pre-broadcast ceremony.)

“The fans deserve everything because I feel like they haven’t been talked about much tonight,” Eilish said. “They’re the only reason anyone is here at all. Guys this is so crazy. I love you all, you guys are amazing.”

She also predicted blowback from fans of other nominated artists.

“I know your fans are hardcore and they’re gonna fight for you,” Eilish said. “I love all fandoms. You guys make this all worth it.”

Eilish beat out hot competitor Lizzo, who slam-dunked the 2020 Grammys nominations with a killer eight nods for her third album, “Cuz I Love You,” with the title track also being nominated in pop and R&B categories.

Eilish scored six nominations for her debut record, “When We All Fall Asleep, Where Do We Go?,” making her the youngest artist ever to earn nods in the top four categories in one year. The darkly sexual “Bad Guy” was the LA native’s first No. 1 hit on Billboard’s Hot 100 chart, but every track on her album has hit that chart since.

About Billie’s competition

Lizzo: The 31-year-old rapper/singer/songwriter/flautist — who aims to be “Aretha Franklin for the 2018 generation” — was born Melissa Jefferson in Detroit and raised in Houston. She overflows with confidence on “Cuz I Love You,” as she turns from soul to funk to pop to R&B on a vintage dime.

Lil Nas X, who won’t be old enough to belly up to the bar until April, was up for six Grammys for his 19-minute EP “7,” which includes the “Old Town Road” remix with Billy Ray Cyrus. The country-rap track topped the Billboard Hot 100 for an unprecedented 19 weeks — only to be dethroned by “Bad Guy” by fellow Gen Z-er Eilish. Lil Nas X, born Montero Lamar Hill in Lithia Springs, Ga., has yet to release a full debut album.

The Black Pumas’ Adrian Quesada, 43, a Grammy-winning guitarist and producer, and Eric Burton, 30, a singer who was busking in downtown Austin, Texas, met through a friend and instantly clicked. The two formed their soul-funk band in 2017 and dropped their self-titled disc in June.

Maggie Rogers, 25, a singer/songwriter and banjo player from Easton, Md., stunned Pharrell Williams when she played a recording of her song “Alaska” at an NYU master class in 2016. The video of the two went viral, and Rogers soon signed with Capitol Records. Formerly more of a folk singer, Rogers added electronica to her style after nightclubbing in Berlin. “Heard It In a Past Life” debuted at No. 2 on Billboard’s Top 200 albums chart.

Rosalía, 26, born Rosalía Vila Tobella outside Barcelona, is known for her pop-flamenco songs, collaborations with Eilish and Harry Styles, recording with Pharrell Williams — and being BFFs with Kylie Jenner. Her sophomore effort, “El Mal Querer,” debuted at No. 1 on Billboard’s Latin Pop Albums chart. The single, “Con altura,” is a reggaeton tribute featuring J Balvin, which Billboard ranked No. 5 on its list of 2019’s best songs.

Tank and the Bangas, a funk, hip-hop, soul, jazz, spoken-word act from New Orleans, is fronted by the glorious Tarriona “Tank” Ball, who sings, cleverly raps and is a poetry-slam champ. Six years after meeting at an open-mic night, the four-member band won NPR’s Tiny Desk Contest in 2017. That achievement led to a record deal with Verve. Their major label debut “Green Balloon” has a floaty, improv feel with a diversity of beats, from sleepy to dance — and references to weed, as heard on the first single. “Smoke.NetFlix.Chill.”

Yola, a 37-year-old Brit born Yolanda Quartey, grew up a fan of Dolly Parton and Aretha Franklin. That inspiration shows. The singer/songwriter’s debut album, “Walk Through Fire,” earned her four Grammy nominations for Best New Artist, Best American Roots Performance, Best American Roots Song and Best Americana Album. It’s no wonder, as her retro country-pop-soul sound, a la Glen Campbell or Dusty Springfield, in songs like “Faraway Look” is captivating. Yola wrote the bluegrass-tinted title track about surviving a house fire.
