Beyonce stars as the adult version of Nala but when the host questioned whether the "Drunk in Love" hitmaker was even in the film Eichner confirmed it is true.
"She's definitely in the movie because I've seen a rough cut," he confirmed. "And I've heard her sing 'Can You Feel the Love Tonight' with Donald Glover and I'm telling you, it's f**king good. And that was never my favorite song to be totally honest."
"I liked it when Elton John sang it. I love Elton John," he continued. "I don't want to give too much away about that, they do not want us talking about it. I will just say that honestly, it made me cry and I was not expecting that."
Rapper and actor Glover will play the adult version of Simba in the live-action remake which will feature completely computer generated visuals.
