Stella Lefty made her Grand Ole Opry debut on Wednesday, performing her breakout hit "Boston" and other songs. She also shared the stage with her country singer boyfriend, Vincent Mason, who was also making his Opry debut.

Kelsea Ballerini found herself defending the country newcomer when people started posting "nepo baby" comments on a video the Opry posted of Stella singing to two St. Jude children in a room backstage.

Some people are questioning her legitimacy as an artist and her quick rise to fame because she's the daughter of a billionaire.

"You can buy a career. You can buy exposure. You can buy opportunities. But you can't buy the years of work, the talent, the connection with fans, or the respect that artists spend decades earning," one user wrote. "And honestly, THAT what's sad to me. Because the Opry is supposed to be bigger than [a] checkbook."

Stella Lefty, whose real name is Stella Lefkofsky, is the daughter of Eric Lefkovsky, who co-founded Groupon and currently serves as the CEO of a health biotech company called Tempus AI. Vanity Fair says his net worth is around $5 billion.

Kelsea Ballerini acknowledged that the Opry is about celebrating tradition but pointed out that it's also about celebrating powerful country music from artists with "different backgrounds and hometowns and generations."

"Y'all in the comments continue to not honor the people the actual Opry house opens its arms to," she wrote. "It's about celebration of all kinds of country music...new, old, traditional, current, however you wanna say it."

"Celebrate music like the Opry does," Kelsea concluded.

In a separate comment, she also reminded fans that the video in question was of Stella singing to two young patients from St. Jude Children's Research Hospital. "Y'all go get some sleep," she added.
