The '21st Century Girl' singer has met the 'Born This Way' star, and said she was struck by her crazy fashion sense and would love to have the same off-the-wall outlook as her.
When asked what meeting Gaga was like, Willow told UK.MSN.com: "She's awesome. She's very explosive and has a very explosive personality - I'd like to be like her."
When asked if she's like to arrive in an egg shaped 'Vessel' like Gaga did to the Grammy Awards this year, Willow, 10, added: "Yeah, probably, so that I don't have to smile to the cameras."
Gaga is not the only star the singer has hung out with recently, after Willow played in support of Justin Bieber when he recently played dates in the UK.
While she said she loves being on tour, she added that Justin can be a little competitive backstage.
She said: "It's awesome because I get to see new places and new people and how the crowd react.
"Justin's very funny. He's plays basketball, like, right before the show, but I stopped because I was like, 'somebody's going to get hurt'. So he won then he ran over and picked me up!"
'21st Century Girl' is released on April 11.
