Never in our wildest dreams could we imagine dating as many hot stars as Taylor Swift! The 27-year-old has gone through a lot of relationships before finding her current boyfriend Joe Alwyn, who — by our count — is No. 15. In case you've forgotten some of them, let's take a walk down memory lane, shall we?

Tom Hiddleston

Taylor and Tom were hot and heavy from June until September of 2016. Fans were shocked because it was SO soon after her split from Calvin, but they quickly got on board. These two were inseparable, and even started dressing alike, until it all came to an end. They still seem to have a mutual respect for one another, and Tom is currently busy reprising his role as Loki in Thor: Ragnarock and Avengers: Infinity War.

Calvin Harris

Calvin will probably always be our fave boyfriend of Tay's. He was sweet, low-key, and actually her longest romance, lasting over a year from February 2015 until June 2016. They even secretly wrote "This Is What You Came For" together! Then Taylor shaded Cal in the "Look What You Made Me Do" video, and he worked with her arch-enemy Katy Perry on "Feels."

Harry Styles

Harry and Tay only allegedly dated for a few months from December 2012 until January 2013, but clearly he left a mark on her heart. Three (maybe four?) of her songs seem to be about him, and they're all super romantic, from "I Knew You Were Trouble" to "Red" to "Style," obvi. Harry even wrote a song about Tay called "Two Ghosts" after he went solo and left One Direction.

Conor Kennedy

Conor and Taylor were smitten with each other from July to October of 2012. They even had hot yacht make-out sessions! It's probably for the best that they didn't end up together, because Conor got arrested after a bar fight in 2016, and Taylor doesn't need that kind of drama in her life. She makes enough of her own.

Jake and Taylor were SUPER public about their relationship. They kissed, cuddled, held hands, and went everywhere together from October 2010 until January 2011.

Cory Monteith

Taylor and Cory never confirmed a relationship, though they both blushed like crazy when they were asked about it. Fans think "Mine" was about Cory after their short romance in April 2010. Sadly, he passed away from a drug overdose in 2013.

John Mayer

John earned himself one of the most bitter songs ever, "Dear John," after their tryst from December 2009 until February 2010. He went on to date Tay's enemy Katy, and is now single, working on his music, and fighting for better gun control.

Drew Hardwick

Okay, so Taylor never actually dated Drew, she just wrote a song about wanting to. He was her high school crush and the subject of "Teardrops On My Guitar." However, it's way better that she didn't date him, because he was arrested with his wife in 2015 for abusing their three-year-old child.
