Olivia Rodrigo Reveals Hilarious British Phrase She Repeated Before Every Guts Tour Show: 'Very Superstitious' (Exclusive)

Olivia Rodrigo may be a Grammy-winning pop superstar, but that doesn’t mean she’s not still a little superstitious from time to time.

The “Vampire” singer, who on Tuesday, Oct. 29 released her Netflix concert special Olivia Rodrigo: GUTS World Tour, tells PEOPLE that she had the same pre-show ritual for every single stop on her tour, which ended earlier this month after nearly 100 shows.

“Kind of a weird superstitious thing that I have — my in-ear monitor tech, his name is Seamus and he’s a very British man. And before every show he says, ‘It’s gonna be a piece of piss,’ which is British for, it’s gonna be easy peasy,” she explains. “And so before every show, I make sure that I say, ‘Seamus, it’s gonna be a piece of piss.’”

Rodrigo, 21, then makes sure Seamus repeats the phrase back to her, lest he conjure any bad luck.

“If he doesn’t say that, I’m convinced it’s going to be a bad show,” she says. “I’m very superstitious.”

Luckily for Rodrigo, her GUTS world tour was a smashing success. After kicking things off in Palm Springs, Calif. in February, she made her way across North America, Europe, Asia and Australia, eventually bringing the cameras along for a show at the Intuit Dome in Los Angeles in August.

Director James Merryman filmed the star’s high-energy set for the concert special, which Rodrigo says she hopes offers fans who didn’t get the chance to make it to a show feel like they’re part of the fun.

“I just wanted to create an experience for people to relive the show and I’m so proud of the show and everyone works so hard to pull it together,” she says. “I was really excited at the prospect of having a little memento that we could watch back forever.”

By the time she got to Los Angeles — which she considers a hometown show, as she grew up in nearby Temecula — the nerves that had plagued her through the early performances were largely gone, though the star says she still got “butterflies” in her stomach before the cameras started rolling.

“I have so many ties here and I find so much inspiration from L.A., and so it just felt really fitting that the concert that will be commemorated is in my favorite city,” she says.

The concert was an extra special one, too, as it featured an unexpected addition to the setlist: a duet of “Hot to Go!” with tour opener and pal Chappell Roan.

Rodrigo says having Roan, 26, along for the ride has been a real treat.

“I think just having support like that really keeps you grounded and reminds you what’s really important,” she says. “She’s been so lovely to me. She’s a little bit older than me, and she gives me such great advice and I’m just so happy for her. I think she deserves all the success in the world.”

The tour also offered Rodrigo the chance to do some good in a place near and dear to her heart: the Philippines, the country from which her great-grandparents emigrated. The singer’s Guts stop marked her first-ever show in the country, and to mark the occasion, Rodrigo donated the show’s net profits to Jhpiego, which provides healthcare to women and children in some of the country’s more rural areas.

“It was probably the highlight of my tour. I was so happy to get to do it,” she says. “I’ve wanted to go my whole life because I’m Filipino. It’s my heritage. And I really wanted to give back and it’s a community who has given so much to me and just welcomed me and champions me, and so it was really important to me to give back to that community.”

With the Guts tour now behind her and a concert special to keep the memories close forever, Rodrigo is ready to move on. The star says she’s “definitely gonna take some off time,” but is always writing new music, as she thinks of it as “self-care.”

“I sort of did everything I wanted to do with that Guts chapter. I made the album and toured it and it was so special and I’m really happy that I got to do it and that it resonated with people the way it did,” she says. “I’m gonna take a break, and then looking forward to what’s next.”
