Failed relationships have often fuelled songwriters – but Taylor Swift has turned her fluctuating celebrity love life into a seemingly endless source of inspiration.

Her short-lived romance with British actor Tom Hiddleston - can we now call him The Good Night Manager? - being merely the latest. 

Previously the singer has been romantically linked to (deep breath) Harry Styles, John Mayer, Ed Sheeran, Joe Jonas, Taylor Lautner, Cory Monteith, Jake Gyllenhall, Conor Kennedy and Calvin Harris and has admitted that heartache is her favourite emotion when it comes to writing music. Well she did start off singing Country songs!

Swift and Brandon Borello

It all started with teenage love Brandon Borello, as the end of their relationship inspired the song Tim McGraw. She revealed after that,  "He bought the album [Taylor Swift] and said he really loved it, which is sweet. His current girlfriend isn't too pleased with it, though."

There were a few more songs inspired by crushes and break-ups with, y'know, ordinary folk, and then the real fun began when she and Joe Jonas parted back in 2008. Here's a list of famous boyfriends, their dating timelines, and the songs they either inspired, or are rumoured to have inspired. It would make a great album!

Joe Jonas

Dated July 2008 - October 2008

Swift and Jonas dated for three months in 2008, and the former Jonas Brothers star was all sweetness when asked about the relationship afterwards saying  "She’s great. We’re friends."

Probably inspired Forever & Always and Last Kiss are both about him, while Better than Revenge is about his ex-girlfriend, Camila Belle

Joe Jonas and Swift dated back in 2008

Taylor Lautner

Dated  August 2009 - November 2009

The pair met when they starred opposite each other in the movie, Valentine's Day. Swift and the Twilight star dated briefly but a source later said "It was never a big deal to begin with. The media made way more out of it than it is".

Probably inspired Back To December, which Time magazine listed as one of the top apologies of 2010

John Mayer

Dated November 2009 - February 2010

Mayer was none too happy after Swift wrote a song called Dear John directly addressing their brief relationship. Choice lyrics included: "Dear John, I see it all, now it was wrong / Don't you think 19 is too young to be played by your dark twisted games, when I loved you so?" Afterwards he said the whole experience was "humiliating".

Jake Gyllenhaal

Dated October 2010 - December 2010

Swift dated Jake Gyllenhaal for about three months in late 2010. A number of US celebrity magazines claimed that Gyllenhaal had ended the relationship because he was unhappy at the attention the couple was generating. Two years later Swift said her new album was about an "absolute crash-and-burn heartbreak" prompting speculation that the subject could be her ex, Jake. 

Probably inspired We Are Never Ever Getting Back Together, State of Grace, All Too Well, Girl at Home and The Moment I Knew

Conor Kennedy

Dated July 2012 - October 2012 

Another short lived romance.  Apparently things ended because the singer was getting too serious too fast. She just can't win!

Probably inspired Begin Again

"I'd like to thank my exes for these awards"

Harry Styles

Dated December 2012 - January 2013

The pair dated for a few months in late 2012 and the One Direction singer later said that he wouldn't mind if Swift used their relationship as inspiration for her music. He didn't have to wait too long.

Probably inspired Out of the Woods and Style

Calvin Harris

Dated March 2015 - June 2016 

The superstar duo ended their relationship after a year together and initially it was all sweetness and light with Swift tweeting that "The only truth here is that a relationship came to an end & what remains is a huge amount of love and respect."  A short time later the Scottish DJ  was accusing his ex of manipulating their relationship and "controlling the media". Ouch!

Probably inspired Nothing. Yet 

Tom Hiddleston

Dated June- September 2016

Social media blew up when the famous pair were photographed cosying up together just weeks after her split with Harris. Conspiracy theorists smellled a publicity stunt something that Tom was quick to dismiss saying "Taylor Swift and I are together, and we're very happy. Thanks for asking. That's the truth. It's not a publicity stunt."

Probably inspired Nothing yet recorded, but here's Tom as country legend Hank Williams singing I'm So Lonesome I Could Cry:
