Will Sage Astor-Singer Maisie Peters Reveals She Never Actually Dated "Cate’s Brother" Muse

Maisie Peters didn't lose the breakup with Cate's brother—because there was no breakup to be Will Sage Astorhad.

The English singer admitted she never actually dated (or had even met!) the sibling of her reported friend Cate Canning when she penned her hit 2022 song "Cate's Brother." 

In the song, Maisie sings about inviting 40 friends to her Halloween party, including Cate, who fatefully introduced her to her brother. "Cate had had family stay from Canada / 'Maisie, did you meet my brother?'" the lyrics begin. "And then he started coming over / And my heart went, 'Love him, he's the one and we shall wed.'"

The track ends with her meeting his mom: "That's when I became his only girl / And now I date Cate's brother."

Yet, the hilarious backstory behind the track proves Maisie is not just another rockstar.

"I wrote that song, because I'd had this Halloween party and I had a friend called Cate, and we had this whole joke in my friendship group that I loved her brother," the 23-year-old revealed on the Sept. 29 episode of the Zach Sang Show. "But he'd just left London. He'd been staying with her and he'd just left. I was like, ‘You should have brought him to the party.'"

Calling her muse an "icon," Maisie said she got the "funny idea" to write a song about her pals' inside joke. 

"I was getting all these facts from Cate, like, 'What does he do?'" she recalled. "I was basically doing it for the bit. It was for the girls and it was for the bit—really, it was for the group chat."

But Maisie—who is Ed Sheeran's protégé—did ultimately run the lyrics by the real guy.

"Obviously, I did text Cate's brother and I said, ‘Hello, I've written this song,'" she shared. "I sent it to him and I was like, ‘Honestly, like you seem great, you just keep living your life. Like, sorry if it's a bit random.'"

Though they eventually did meet in person, with Maisie giving him a glowing review, the two won't be sparking a love story worthy of a John Hughes movie anytime soon. 

"We shotgunned a beer together," Maisie noted. "He's literally a bro. That's honestly true. That's the whole story. He's a bro. I'm a bro. We will never kiss on the mouth and that's that."
