Travis and his brother Jason spoke about the Eras Tour meeting on the latest episode of their podcast New Heights today.
He admitted he thought the prince was “so cool” but he didn’t know how to address him.
Travis said: “I wasn’t sure if I was supposed to bow to them, curtsy or just be an American idiot and shake their hand.”
Prince William took his eldest children George and Charlotte to Taylor Swift’s Eras Tour concert at Wembley Stadium on Saturday night.
William, who was celebrating his 42nd birthday, posted a selfie with the global superstar the next day with the caption: “Thankyou Taylor Swift for a great evening!”
Swift also shared a cute snap she took after the gig with William, George, Charlotte and her American football player boyfriend Travis.
She wrote: “Happy Bday M8! London shows are off to a splendid start.”
George, 10, grinned in a blue buttoned Ralph Lauren shirt and jeans, while Charlotte, nine, donned a sparkly top for their big night out.
Footage posted online showed William dancing in the crowd among thousands of fans as Swift sang her hit Shake It Off.
Travis told his podcast listeners: “We met royalty, guys. There was royalty at the show. I got there early and got to meet Prince William. How bout that? Your Royal Highness.”
He said: “Because we weren’t at an elegant, official royal event, we didn’t have to bow. “If it would’ve been an official meeting-of-royalty event, then it would have been that.”
Travis joked he’d never seen his brother more respectful, saying he saw Jason put his beer “ten feet away”.
Jason added: “They were wonderful people, and that’s what it’s about. They’re part of a monarchy [it’s] hard to be a down-to-earth human being – I would assume. But [they] came off that way completely.”
The brothers gushed over “superstar” Princess Charlotte’s “fire”, revealing she was full of questions.
Travis praised William and Kate’s parenting, added of Charlotte: “She had fire to her. She was asking questions… I love it when parents ask their kids to be present, be vocal… Encourage them to take a lead in the conversation.”
