Singing legend Dionne Warwick isn’t sure what a “hologram tour” is, she said, but she thinks it’s stupid.

While at an event for the Community Anti-Drug Coalitions of America, the 78-year-old Warwick was asked about plans for an upcoming Whitney Houston hologram tour.

"I haven't a clue as to what that is. It's surprising to me," Warwick, who is Houston's cousin, told ET. "I don't know what it is. I think it's stupid, but whatever it is that's what it is."

The New York Times reported that Pat Houston, Whitney Houston's sister-in-law and executor of the late vocalist's estate, signed a deal with music company Primary Wave Music Publishing to rebuild the singer's business.

Warwick also had an opinion on today’s generation of singers.

In an interview with Essence, the woman who has “given us 58 years of chart-topping classics,” said there are no classics today.

"I don't know if 10 years from now, anybody can actually sing the songs of our babies today. That's not, as you guys say, 'throwing shade,' it's looking at it with reality," she said.

Not even Beyoncé?

“I have an admiration for Beyoncé Knowles, Carter now. Watching her growth has been quite refreshing. It’s wonderful to see how she’s been able to create what and who she wanted to be and who she is… very proud of that, I really am,” Warwick told the magazine.

“Now sustaining and becoming a big icon that Gladys Knight, or Patti LaBelle, or Johnny Mathis, or Frank Sinatra, or Sammy Davis Jr. is? I doubt that.”
