Rodrigo recently revealed the one question she always asks on a first date

It seems Olivia Rodrigo and Grimes both agree on “oddly specific” dating “red flag.”

After the “Vampire” singer, 21, shared that one of her dating “red flags” is if a guy says he wants to go to space during an interview with Netflix posted on Instagram on Friday, Nov. 1, the “Oblivion” musician, 36, appeared to be aligned with her, seemingly trolling her ex Elon Musk on Sunday, Nov. 3.

In response to a Pop Crave post about the clip on X (formerly Twitter) that read “Olivia Rodrigo reveals that a guy wanting to go to space is a red flag for her,” Grimes replied: “It’s true. Only women should be going to space.”

It’s true. Only women should be going to space.

Rodrigo’s dating “red flag” initially came up when she was discussing the signature tees she wore during the Guts World Tour, including one that read “Dump Him” — which Rodrigo said is a “classic homage to Miss Britney Spears.” From there, the “good 4 u” hitmaker discussed the one question she asks guys on first dates to gauge their compatibility.

“The biggest red flag, OK, this is a very oddly specific question that I ask guys on first dates,” Rodrigo began. “I always ask them if they would want to go to space.”

“And if they say yes, I don’t date them,” she continued. “I just think if you want to go to space, you’re a little too full of yourself.”

Grimes and the X founder, 53, were first linked in May 2018 when they made their public debut at the Met Gala. In a cover story interview with Vanity Fair in April 2022, the Canadian pop star described her relationship with Musk as “very fluid.”

After an on-and-off-again relationship with the billionaire entrepreneur, Grimes clarified in a tweet that the couple had broken up again since the Vanity Fair interview, adding, “he’s my best friend and the love of my life.”

While Musk is a father to nine other children with two other women, he and Grimes share 4-year-old son X Æ A-12, 2½-year-old daughter Exa Dark Sideræl and son Techno Mechanicus, who was born in 2022.

In March, roughly two years after she and Musk called it quits for the third and final time, Grimes announced her romance with DJ Anyma on Instagram.
