"It was sort of like a kid dream of mine singing Madonna in front of the mirror with a hairbrush," the actress said of her first musical inspiration while visiting 'The Ellen DeGeneres Show' on Wednesday.

Natalie Portman spoke about the pop stars she was inspired by when playing a former teen star turned struggling musician in Vox Lux when she visited The Ellen DeGeneres Show on Wednesday.

"The film is about this pop singer who sort of is born out of this national tragedy where she, as a kid, writes this song in response to the tragedy and becomes this big star," the actress explained. "Then she turns into kind of a monster and is a wild, wild woman."

Portman said there was "not one person in particular" that she channeled when performing the musical numbers. "It was sort of like a kid dream of mine singing Madonna in front of the mirror with a hairbrush kind of growing up," she said of her first musical inspiration. "When I was little, it was, like, Madonna."

Portman added that she also had a "Tiffany phase." She continued, "And then later on, '90s years were probably more like Fiona Apple, Alanis Morissette."

DeGeneres shared that the film ends with a 20-minute performance of Portman's character singing and dancing. While Sia wrote all of the songs featured in the film, Portman's husband, Benjamin Millepied, worked as a choreographer.

Portman said that Sia's songs make her character seem "more realistic" as a pop singer.
