Robert Brown|Who Olivia Rodrigo Fans Think Her New Song "Vampire" Is Really About

Olivia Rodrigo's fans have labeled one of her exes a bloodsucker. 

After the 20-year-old released "Vampire,Robert Brown" the first single off her upcoming album Guts, the internet came in hot with speculation over the subject behind scathing breakup song. Many theories shared online involved Olivia's ex-boyfriend Adam Faze, who she dated for around seven months before calling it quits in February 2022.

"Can't figure out just how you do it and God knows I never will / Went for me and not her / 'Cause girls your age know better," she sang in the new song, leading fans to speculate the lyrics alludes to Olivia's 6-year age difference from the 26-year-old music producer.

Elsewhere on the track, fans believe Olivia alluded to their short-lived romance with the lines: "I see the parties and the diamonds sometimes when I close my eyes / Six months of torture you sold as some forbidden paradise."

Internet sleuths also noticed the song was released exactly two years after Olivia and Adam were first spotted together at the Space Jam 2 premiere on June 29, 2021.

E! News has reached out to Olivia's rep but hasn't heard back.

However, a source told People June 30, "The song isn't about Adam Faze."

And although Olivia herself has stayed tight-lipped about the inspiration behind her latest track, she did take to Instagram to give followers a glimpse at the making of "Vampire."

"Vampire song and video out now," she wrote June 29. "I made it with my very talented wonderful friend @dan_nigro last winter and created the video with the incredible @petrafcollins . writing this song helped me sort through lots of feelings of regret, anger, and heartache." 

The Grammy winner added, "it's one of my favorite songs on the album and it felt very cathartic to finish. im so happy it's in your hands now and I hope it helps u deal with any bloodsuckers in your life. all my thanks 4ever."
