Who is Robo Girl on The Masked Singer US? Show clues

Here’s what the clue revealed about Robo Girl: "While on Tour, Robo Girl Holds Her Own Opposite Multi-Grammy Winner."

And here’s what Robo Girl said during her clue package: "Stepping up into the spotlight on Andrew Lloyd Webber night feels a little bit out of my comfort zone. Because for much of my career, I’ve lived in the shadow of superstars. From Pharrell to even David Blaine, the glow of their talent made it hard for me to recognize my own. I was worried it would never be my time. But with 86 cents to my name, I booked a job that would change my life forever. I not only found my own pretty little spotlight, but gained the most magical fandom in the world. They’ve given me supernatural confidence and I’m going to need that if I’m going to take the lead tonight. Places, everyone."

During her clue package on Muppets Night, Robo Girl had more to say about defeating Mermaid, who ended up being music legend Gloria Gaynor. "Last week’s battle royale was totally surreal. Beating the mermaid still does not commute. She’s a legend and it feels euphoric to have received my crown in her presence. So in her honor I better survive tonight against these two new challengers. I’m going to put up my firewall and keep this crown under lockdown. Now before I reboot my next performance on stage, I command you to download this clue. [Lindsay Lohan]. Does this mean anything to you?"
