POP princess Sabrina Carpenter has the making of a great queen, says a butler who taught her how to behave like a royal.
Grant Harrold gave the US star etiquette lessons before an awards bash.
He said the Espresso singer “rolled her eyes” at the start but was “very natural”.
Footage unearthed by The Sun shows Sabrina, then 18, learning to serve afternoon tea.
She also balanced books on her head to improve posture.
Grant, who worked for the then-Prince Charles from 2007 to 2011, said the stunt ahead of the 2017 MTV Awards was more “Downton Abbey than Mean Girls”.
He added: “She’s very chilled, laid-back and didn’t act like a superstar.
“If we could’ve got her into a tiara, she’d have been up for it. She began eye-rolling at the start. She wasn’t too sure.
“Her curtsy was a bit too theatrical. Perfect for one of her shows, not for meeting the King. But she was very natural. I didn’t have to confiscate anything. She was very good about her phone.
“She could pass at the Palace quite easily.
“I can see her getting along with William and Kate, and the King.
“She’s charming, confident, assertive. She’d make a future great queen. A few etiquette lessons and she’d be there.”
Sabrina was joined by US comedians the Dolan twins at a London hotel — perfecting the skills of pauper-turned-socialite Eliza Doolittle — Audrey Hepburn in 1964 film My Fair Lady.
Now 26, Anglophile Sabrina recorded much of new album Man’s Best Friend in the Cotswolds.
And she posed with a sparkly Union Jack on her tour in March.
