Clayton Collins, "Tim McGraw"
Collins—with his piercing blue eyes and emo-style hair (which was all the rage back then)—was an actor cast to play Swift's Chevy-driving boyfriend in "Tim Mcgraw."
Tyler Hilton, "Tear Drops on My Guitar"
We'll never forget the heart-breaking story of hunky Hilton (aka Drew) falling for another girl in the singer's "Teardrops on My Guitar."
Toby Hemingway, "Mine"
With his bright blonde hair and piercing blue eyes, Hemingway made our hearts flutter as he took Swift's hand in marriage in "Mine." You also might recognize him from The Covenant, Black Swan or Into the Darkness.
Justin Gaston, "Love Story"
While you may remember Gaston from his days dating Miley Cyrus or his time on the reality TV series Nashville Star, we remember him for playing Romeo in Swift's "Love Story."
Guntars Asmanis, "Back to December"
A male model from Latvia, Asmanis has strutted his stuff for Louis Vuitton and Miu Miu, but most importantly, he played Swift's former lover in "Back to December."
Zach Gilford, "Ours"
We love a man in uniform, and Gilford did it justice when he played Swift's military boyfriend in "Ours."
Justin Sandy, "Picture to Burn"
Sandy was a retired NFL player who took to acting after his days on the field. He also played the pickup-truck-driving dude in the picture Swift hoped to burn.
Lucas Till, "You Belong With Me"
We still smile whenever we see a GIF of Till holding up the "Wish You Were" sign in "You Belong With Me." He's such a cutie!
Stephen Colletti, "White Horse"
OK, so Colletti was the southern Cali boyfriend of our dreams when we watched him on Laguna Beach, but he only became even swoonier (we made that word up) when he debuted his "face of an angel" in Swift's "White Horse" music video.
Noah Mills, "We Are Never Ever Getting Back Together"
We couldn't help but compare Mills—a Canadian model and actor—to Adam Levine in Swift's "We Are Never Ever Getting Back Together." To be honest, we don't blame her for constantly letting him back in.
Reeve Carney, "I Knew You Were Trouble"
Not only did Carney play Peter Parker in Broadway's Spider-Man: Turn Off the Dark, he also played Swift's partying-hard indie boyfriend in "I Knew You Were Trouble."
Vladimir Perrin, "Begin Again"
This French actor and Ryan Gosling look-alike nabbed the titular role in Swift's Parisian-themed "Begin Again," stealing her heart on a Wednesday in a café.
Dominic Sherwood, "Style"
You may know him for his role in Shadowhunters: The Mortal Instruments, but we remember Sherwood for playing Swift's dream-worthy love interest in "Style."
Sean O'Pry, "Blank Space"
Swoon, swoon, swoon! That's literally the only word to describe O'Pry in "Blank Space." Fortunately, he's a model so we get to see him quite often. Fun fact: he was 2013's highest-paid male model after appearing in this music video.
Scott Eastwood, "Wildest Dreams"
We've never doubted Eastwood's hotness, and his appearance in "Wildest Dreams" only heightened our obsession.
