If charisma were a currency, Katy Perry could buy out half of Beverly Hills and still have enough left for world tour confetti. With her megawatt smile, candy-coated charm, and a voice that could sell both teenage dreams and divorce anthems, the California-born pop star is an undeniable force of attraction. Add to that the ability to juggle wigs, wisdom, and world records, and one begins to understand why romantic hopefuls from multiple industries lined up for a spot in her heart. Which brings us, quite naturally, to the next part.

Being in the industry for over two decades, Katy Perry has love stories that could make a therapist blush and a novelist take notes.

1. Matt Thiessen

Before the whipped cream bras and chart-toppers, there was Matt Thiessen, the Christian rocker who co-wrote melodies with Katy Perry when she was still swapping Bibles for ballads. Their 2003–2005 romance was wholesome, melodic, and largely off the radar.

 Thiessen, the frontman of Relient K, later praised Perry as a good friend, which is a polite way of saying they broke up and still send the occasional Christmas emoji. Rumor has it Kelly Clarkson even sang one of their co-creations.

2. Johnny Lewis

Katy Perry’s 2005–2006 relationship with Johnny Lewis began as a Hollywood dream and ended somewhere between heartbreak and self-preservation. Lewis, known for ‘Sons of Anarchy’, reportedly struggled with personal demons Perry could not save him from.

 She ended it to focus on her career, but sources say she was devastated by his death in 2012. Songs like ‘The One That Got Away’ and ‘Circle the Drain’ are said to reflect their complicated love and its darker fallout.

3. Travie McCoy

If heartbreak had a soundtrack, Katy Perry’s 2006–2008 relationship with Gym Class Heroes frontman Travie McCoy would play on loop. They shared stages, eyeliner, and eventually, a messy goodbye via email. McCoy later cited substance struggles; Perry chose her career over codependency. 

‘Circle the Drain’ is also widely theorised to be aimed at him, which is poetic justice in four minutes and forty seconds. He called it hurtful and he called it art while history called it inevitable.

4. Josh Groban

This one barely counts as a fling but was memorable enough to make headlines. Katy Perry and Josh Groban were briefly linked in early 2009, and although they both insisted on friendship, Perry once called him “the one that got away” during a livestream. 

Groban, ever the soft-voiced gentleman, said he was surprised but flattered. Their relationship may have lasted as long as a Starbucks order, but it left just enough intrigue for fans to romanticize.

5. Russell Brand

Katy Perry’s 2009–2012 whirlwind romance with Russell Brand was part honeymoon, part headline, and part HBO drama. They were engaged within months, married in India with elephants, and divorced by text message. Perry later accused Brand of resenting her success and being controlling; he called it “normal, human reasons.” 

Songs like ‘By The Grace of God’ and ‘Wide Awake’ captured the fallout. Love may be blind, but this marriage definitely needed reading glasses.

6. Robert Ackroyd

In the spring of 2012, Katy Perry tried her hand at rock ‘n’ roll romance with Robert Ackroyd, guitarist for Florence + the Machine. The affair barely outlived a flower crown at Coachella. Their work commitments collided, and Perry, invoking déjà vu from her Russell Brand saga, gave him the “you do you” treatment. 

Whispers of a 2014 rekindling surfaced but vanished like glitter after a rainstorm, pretty, intriguing, and ultimately impossible to confirm. And then yet another romantic spark, swept fans away from the Robert Ackroyd chapter.

7. John Mayer

Katy Perry’s most melodically tortured chapter arrived courtesy of John Mayer, America’s favorite crooner turned commitment magician. Their on-again, off-again rhythm from 2012 to 2015 inspired duets, drama, and songs with more subtext than a Jane Austen seminar. 

They sang ‘Who You Love’, but reportedly forgot to discuss how. Mayer, whose complicated timeline with Taylor Swift that the internet loves to look back on, admitted ‘Still Feel Like Your Man’ was about her, which feels less like closure and more like poetic damage control.

8. Diplo

Diplo and Katy Perry were briefly linked in 2014, though calling it a romance may overstate what was, by most accounts, a Coachella flirtation with festival passes. While Diplo craved commitment, Perry preferred pyrotechnics over paperwork.

 Later, when Perry ranked her lovers on national radio, Diplo placed a gracious third. He replied with all the bewilderment of a man still checking his messages for proof it happened. Romance, in this case, was a group text with poor reception.

9. Orlando Bloom

Orlando Bloom and Katy Perry had a love story worthy of an epic poem, or a group therapy session. Their years together (2016–2025, with intermissions) included a postponed wedding, a baby named Daisy Dove, and enough couples therapy to fund a therapist’s beach house. 

Ultimately, they cited communication issues and career pressures. From a Golden Globes afterparty to a separation press release, theirs was a Hollywood romance that tried very hard to be human.

10. Justin Trudeau

In July 2025, the internet momentarily combusted when Katy Perry and Justin Trudeau were spotted dining in Montreal. No one knew if it was a date, a diplomatic dinner, or a well-lit PR accident. Sources clashed, Twitter spiraled, and Perry continued her ‘Lifetimes’ tour while Trudeau waved from the audience like a man unsure whether to send flowers or just a polite text.

Whatever it was, it made headlines, and likely left a few government staffers checking their NDAs. Much like her discography, Katy Perry’s love life has been a symphony of bold choices, unexpected turns, and unforgettable moments. If these romances were songs, they would come with hidden tracks, bonus verses, and one irresistible hook that lingers long after the final note.
